(c) Open Platform for NFV Project, Inc. and its contributors ********************* OPNFV Fuel User Guide ********************* Abstract ======== This document contains details about using OPNFV Fuel ``Gambia`` release after it was deployed. For details on how to deploy OpenStack, check the installation instructions in the :ref:`fuel_userguide_references` section. This is an unified documentation for both ``x86_64`` and ``aarch64`` architectures. All information is common for both architectures except when explicitly stated. Network Overview ================ Fuel uses several networks to deploy and administer the cloud: +------------------+----------------------------------------------------------+ | Network name | Description | | | | +==================+==========================================================+ | **PXE/admin** | Used for booting the nodes via PXE and/or Salt | | | control network | +------------------+----------------------------------------------------------+ | **mcpcontrol** | Used to provision the infrastructure hosts (Salt & MaaS) | +------------------+----------------------------------------------------------+ | **management** | Used for internal communication between | | | OpenStack components | +------------------+----------------------------------------------------------+ | **internal** | Used for VM data communication within the | | | cloud deployment | +------------------+----------------------------------------------------------+ | **public** | Used to provide Virtual IPs for public endpoints | | | that are used to connect to OpenStack services APIs. | | | Used by Virtual machines to access the Internet | +------------------+----------------------------------------------------------+ These networks - except ``mcpcontrol`` - can be Linux bridges configured before the deploy on the Jumpserver. If they don't exists at deploy time, they will be created by the scripts as ``libvirt`` managed networks. Network ``mcpcontrol`` ~~~~~~~~~~~~~~~~~~~~~~ ``mcpcontrol`` is a virtual network, managed by libvirt. Its only purpose is to provide a simple method of assigning an arbitrary ``INSTALLER_IP`` to the Salt master node (``cfg01``), to maintain backwards compatibility with old OPNFV Fuel behavior. Normally, end-users only need to change the ``INSTALLER_IP`` if the default CIDR (``10.20.0.0/24``) overlaps with existing lab networks. ``mcpcontrol`` has both NAT and DHCP enabled, so the Salt master (``cfg01``) and the MaaS VM (``mas01``, when present) get assigned predefined IPs (``.2``, ``.3``, while the jumpserver bridge port gets ``.1``). +------------------+---------------------------+-----------------------------+ | Host | Offset in IP range | Default address | +==================+===========================+=============================+ | ``jumpserver`` | 1st | ``10.20.0.1`` | +------------------+---------------------------+-----------------------------+ | ``cfg01`` | 2nd | ``10.20.0.2`` | +------------------+---------------------------+-----------------------------+ | ``mas01`` | 3rd | ``10.20.0.3`` | +------------------+---------------------------+-----------------------------+ This network is limited to the ``jumpserver`` host and does not require any manual setup. Network ``PXE/admin`` ~~~~~~~~~~~~~~~~~~~~~ .. TIP:: ``PXE/admin`` does not usually use an IP range offset in ``IDF``. .. NOTE:: During ``MaaS`` commissioning phase, IP addresses are handed out by ``MaaS``'s DHCP. .. WARNING:: Default addresses in below table correspond to a ``PXE/admin`` CIDR of ``192.168.11.0/24`` (the usual value used in OPNFV labs). This is defined in ``IDF`` and can easily be changed to something else. ..

To login as ``ubuntu`` user, use the RSA private key ``/var/lib/opnfv/mcp.rsa``: .. code-block:: console jenkins@jumpserver:~$ ssh -o StrictHostKeyChecking=no \ -i /var/lib/opnfv/mcp.rsa \ -l ubuntu 10.20.0.2 ubuntu@cfg01:~$ .. NOTE:: User ``ubuntu`` has sudo rights. .. TIP:: The Salt master IP (``10.20.0.2``) is not hard set, it is configurable via ``INSTALLER_IP`` during deployment. .. TIP:: Starting with the ``Gambia`` release, ``cfg01`` is containerized, so this also works (from ``jumpserver`` only): .. code-block:: console jenkins@jumpserver:~$ docker exec -it fuel bash root@cfg01:~$ Accessing Cluster Nodes ======================= Logging in to cluster nodes is possible from the Jumpserver, Salt Master etc. .. code-block:: console jenkins@jumpserver:~$ ssh -i /var/lib/opnfv/mcp.rsa ubuntu@192.168.11.52 .. TIP:: ``/etc/hosts`` on ``cfg01`` has all the cluster hostnames, which can be used instead of IP addresses. .. code-block:: console root@cfg01:~$ ssh -i ~/fuel/mcp/scripts/mcp.rsa ubuntu@ctl01 Debugging ``MaaS`` Comissioning/Deployment Issues ================================================= One of the most common issues when setting up a new POD is ``MaaS`` failing to commission/deploy the nodes, usually timing out after a couple of retries. Such failures might indicate misconfiguration in ``PDF``/``IDF``, ``TOR`` switch configuration or even faulty hardware. Here are a couple of pointers for isolating the problem. Accessing the ``MaaS`` Dashboard ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``MaaS`` web-based dashboard is available at ``http://:5240/MAAS``, e.g. ``http://172.16.10.12:5240/MAAS``. The administrator credentials are ``opnfv``/``opnfv_secret``. .. NOTE:: ``mas01`` VM does not automatically get assigned an IP address in the public network segment. If ``MaaS`` dashboard should be accesiable from the public network, such an address can be manually added to the last VM NIC interface in ``mas01`` (which is already connected to the public network bridge). Ensure Commission/Deploy Timeouts Are Not Too Small ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Some hardware takes longer to boot or to run the initial scripts during commissioning/deployment phases. If that's the case, ``MaaS`` will time out waiting for the process to finish. ``MaaS`` logs will reflect that, and the issue is usually easy to observe on the nodes' serial console - if the node seems to PXE-boot the OS live image, starts executing cloud-init/curtin hooks without spilling critical errors, then it is powered down/shut off, most likely the timeout was hit. To access the serial console of a node, see your board manufacturer's documentation. Some hardware no longer has a physical serial connector these days, usually being replaced by a vendor-specific software-based interface. If the board supports ``SOL`` (Serial Over LAN) over ``IPMI`` lanplus protocol, a simpler solution to hook to the serial console is to use ``ipmitool``. .. TIP:: Early boot stage output might not be shown over ``SOL``, but only over the video console provided by the (vendor-specific) interface. .. code-block:: console jenkins@jumpserver:~$ ipmitool -H -U -P \ -I lanplus sol activate To bypass this, simply set a larger timeout in the ``IDF``. Check Jumpserver Network Configuration ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. code-block:: console jenkins@jumpserver:~$ brctl show jenkins@jumpserver:~$ ifconfig -a +-----------------------+------------------------------------------------+ | Configuration item | Expected behavior | +=======================+================================================+ | IP addresses assigned | IP addresses should be assigned to the bridge, | | to bridge ports | and not to individual bridge ports | +-----------------------+------------------------------------------------+ Check Network Connectivity Between Nodes on the Jumpserver ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ``cfg01`` is a Docker container running on the ``jumpserver``, connected to Docker networks (created by docker-compose automatically on container up), which in turn are connected using veth pairs to their ``libvirt`` managed counterparts. For example, the ``mcpcontrol`` network(s) should look like below. .. code-block:: console jenkins@jumpserver:~$ brctl show mcpcontrol bridge name bridge id STP enabled interfaces mcpcontrol 8000.525400064f77 yes mcpcontrol-nic veth_mcp0 vnet8 jenkins@jumpserver:~$ docker network ls NETWORK ID NAME DRIVER SCOPE 81a0fdb3bd78 docker-compose_docker-mcpcontrol macvlan local [...] jenkins@jumpserver:~$ docker network inspect docker-compose_mcpcontrol [ { "Name": "docker-compose_mcpcontrol", [...] "Options": { "parent": "veth_mcp1" }, } ] Before investigating the rest of the cluster networking configuration, the first thing to check is that ``cfg01`` has network connectivity to other jumpserver hosted nodes, e.g. ``mas01`` and to the jumpserver itself (provided that the jumpserver has an IP address in that particular network segment). .. code-block:: console jenkins@jumpserver:~$ docker exec -it fuel bash root@cfg01:~# ifconfig -a | grep inet inet addr:10.20.0.2 Bcast:0.0.0.0 Mask:255.255.255.0 inet addr:172.16.10.2 Bcast:0.0.0.0 Mask:255.255.255.0 inet addr:192.168.11.2 Bcast:0.0.0.0 Mask:255.255.255.0 For each network of interest (``mcpcontrol``, ``mgmt``, ``PXE/admin``), check that ``cfg01`` can ping the jumpserver IP in that network segment, as well as the ``mas01`` IP in that network. .. NOTE:: ``mcpcontrol`` is set up at VM bringup, so it should always be available, while the other networks are configured by Salt as part of the ``virtual_init`` STATE file. .. code-block:: console root@cfg01:~# ping -c1 10.20.0.1 # mcpcontrol jumpserver IP root@cfg01:~# ping -c1 10.20.0.3 # mcpcontrol mas01 IP .. TIP:: ``mcpcontrol`` CIDR is configurable via ``INSTALLER_IP`` env var during deployment. However, IP offsets inside that segment are hard set to ``.1`` for the jumpserver, ``.2`` for ``cfg01``, respectively to ``.3`` for ``mas01`` node. .. code-block:: console root@cfg01:~# salt 'mas*' pillar.item --out yaml \ _param:infra_maas_node01_deploy_address \ _param:infra_maas_node01_address mas01.mcp-ovs-noha.local: _param:infra_maas_node01_address: 172.16.10.12 _param:infra_maas_node01_deploy_address: 192.168.11.3 root@cfg01:~# ping -c1 192.168.11.1 # PXE/admin jumpserver IP root@cfg01:~# ping -c1 192.168.11.3 # PXE/admin mas01 IP root@cfg01:~# ping -c1 172.16.10.1 # mgmt jumpserver IP root@cfg01:~# ping -c1 172.16.10.12 # mgmt mas01 IP .. TIP:: Jumpserver IP addresses for ``PXE/admin``, ``mgmt`` and ``public`` bridges are user-chosen and manually set, so above snippets should be adjusted accordingly if the user chose a different IP, other than ``.1`` in each CIDR. Alternatively, a quick ``nmap`` scan would work just as well. .. code-block:: console root@cfg01:~# apt update && apt install -y nmap root@cfg01:~# nmap -sn 10.20.0.0/24 # expected: cfg01, mas01, jumpserver root@cfg01:~# nmap -sn 192.168.11.0/24 # expected: cfg01, mas01, jumpserver root@cfg01:~# nmap -sn 172.16.10.0/24 # expected: cfg01, mas01, jumpserver Check ``DHCP`` Reaches Cluster Nodes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ One common symptom observed during failed commissioning is that ``DHCP`` does not work as expected between cluster nodes (baremetal nodes in the cluster; or virtual machines on the jumpserver in case of ``hybrid`` deployments) and the ``MaaS`` node. To confirm or rule out this possibility, monitor the serial console output of one (or more) cluster nodes during ``MaaS`` commissioning. If the node is properly configured to attempt PXE boot, yet it times out waiting for an IP address from ``mas01`` ``DHCP``, it's worth checking that ``DHCP`` packets reach the ``jumpserver``, respectively the ``mas01`` VM. .. code-block:: console jenkins@jumpserver:~$ sudo apt update && sudo apt install -y dhcpdump jenkins@jumpserver:~$ sudo dhcpdump -i admin_br .. TIP:: If ``DHCP`` requests are present, but no replies are sent, ``iptables`` might be interfering on the jumpserver. Check ``MaaS`` Logs ~~~~~~~~~~~~~~~~~~~ If networking looks fine, yet nodes still fail to commission and/or deploy, ``MaaS`` logs might offer more details about the failure: * ``/var/log/maas/maas.log`` * ``/var/log/maas/rackd.log`` * ``/var/log/maas/regiond.log`` .. TIP:: If the problem is with the cluster node and not on the ``MaaS`` server, node's kernel logs usually contain useful information. These are saved via rsyslog on the ``mas01`` node in ``/var/log/maas/rsyslog``. Recovering Failed Deployments ============================= The first deploy attempt might fail due to various reasons. If the problem is not systemic (i.e. fixing it will not introduce incompatible configuration changes, like setting a different ``INSTALLER_IP``), the environment is safe to be reused and the deployment process can pick up from where it left off. Leveraging these mechanisms requires a minimum understanding of how the deploy process works, at least for manual ``STATE`` runs. Automatic (re)deploy ~~~~~~~~~~~~~~~~~~~~ OPNFV Fuel's ``deploy.sh`` script offers a dedicated argument for this, ``-f``, which will skip executing the first ``N`` ``STATE`` files, where ``N`` is the number of ``-f`` occurrences in the argument list. .. TIP:: The list of ``STATE`` files to be executed for a specific environment depends on the OPNFV scenario chosen, deployment type (``virtual``, ``baremetal`` or ``hybrid``) and the presence/absence of a ``VCP`` (virtualized control plane). e.g.: Let's consider a ``baremetal`` enviroment, with ``VCP`` and a simple scenario ``os-nosdn-nofeature-ha``, where ``deploy.sh`` failed executing the ``openstack_ha`` ``STATE`` file. The simplest redeploy approach (which usually works for **any** combination of deployment type/VCP/scenario) is to issue the same deploy command as the original attempt used, then adding a single ``-f``: .. code-block:: console jenkins@jumpserver:~/fuel$ ci/deploy.sh -l -p \ -s [...] \ -f # skips running the virtual_init STATE file All ``STATE`` files are re-entrant, so the above is equivalent (but a little slower) to skipping all ``STATE`` files before the ``openstack_ha`` one, like: .. code-block:: console jenkins@jumpserver:~/fuel$ ci/deploy.sh -l -p \ -s [...] \ -ffff # skips virtual_init, maas, baremetal_init, virtual_control_plane .. TIP:: For fine tuning the infrastructure setup steps executed during deployment, see also the ``-e`` and ``-P`` deploy arguments. .. NOTE:: On rare occassions, the cluster cannot idempotently be redeployed (e.g. broken MySQL/Galera cluster), in which case some cleanup is due before (re)running the ``STATE`` files. See ``-E`` deploy arg, which allows either forcing a ``MaaS`` node deletion, then redeployment of all baremetal nodes, if used twice (``-EE``); or only erasing the ``VCP`` VMs if used only once (``-E``). Manual ``STATE`` Run ~~~~~~~~~~~~~~~~~~~~ Instead of leveraging the full ``deploy.sh``, one could execute the ``STATE`` files one by one (or partially) from the ``cfg01``. However, this requires a better understanding of how the list of ``STATE`` files to be executed is constructed for a specific scenario, depending on the deployment type and the cluster having baremetal nodes, implemented in: * ``mcp/config/scenario/defaults.yaml.j2`` * ``mcp/config/scenario/.yaml`` e.g.: For the example presented above (baremetal with ``VCP``, ``os-nosdn-nofeature-ha``), the list of ``STATE`` files would be: * ``virtual_init`` * ``maas`` * ``baremetal_init`` * ``virtual_control_plane`` * ``openstack_ha`` * ``networks`` To execute one (or more) of the remaining ``STATE`` files after a failure: .. code-block:: console jenkins@jumpserver:~$ docker exec -it fuel bash root@cfg01:~$ cd ~/fuel/mcp/config/states root@cfg01:~/fuel/mcp/config/states$ ./openstack_ha root@cfg01:~/fuel/mcp/config/states$ CI_DEBUG=true ./networks For even finer granularity, one can also run the commands in a ``STATE`` file one by one manually, e.g. if the execution failed applying the ``rabbitmq`` sls: .. code-block:: console root@cfg01:~$ salt -I 'rabbitmq:server' state.sls rabbitmq Exploring the Cloud with Salt ============================= To gather information about the cloud, the salt commands can be used. It is based around a master-minion idea where the salt-master pushes config to the minions to execute actions. For example tell salt to execute a ping to ``8.8.8.8`` on all the nodes. .. code-block:: console root@cfg01:~$ salt "*" network.ping 8.8.8.8 ^^^ target ^^^^^^^^^^^^ function to execute ^^^^^^^ argument passed to the function .. TIP:: Complex filters can be done to the target like compound queries or node roles. For more information about Salt see the :ref:`fuel_userguide_references` section. Some examples are listed below.

An ``x86_64`` deployment also supports ``non-UEFI`` images, however that choice is up to the underlying hardware and the administrator to make. The images for the above operating systems can be found in their respective websites. OpenStack Storage ================= OpenStack Cinder is the project behind block storage in OpenStack and OPNFV Fuel supports LVM out of the box. By default ``x86_64`` supports 2 additional block storage devices, while ``aarch64`` supports only one. More devices can be supported if the OS-image created has additional properties allowing block storage devices to be spawned as ``SCSI`` drives. To do this, add the properties below to the server: .. code-block:: console root@ctl01:~$ openstack image set --property hw_disk_bus='scsi' \ --property hw_scsi_model='virtio-scsi' \ The choice regarding which bus to use for the storage drives is an important one. ``virtio-blk`` is the default choice for OPNFV Fuel, which attaches the drives in ``/dev/vdX``. However, since we want to be able to attach a larger number of volumes to the virtual machines, we recommend the switch to ``SCSI`` drives which are attached in ``/dev/sdX`` instead. ``virtio-scsi`` is a little worse in terms of performance but the ability to add a larger number of drives combined with added features like ZFS, Ceph et al, leads us to suggest the use of ``virtio-scsi`` in OPNFV Fuel for both architectures. More details regarding the differences and performance of ``virtio-blk`` vs ``virtio-scsi`` are beyond the scope of this manual but can be easily found in other sources online like `VirtIO SCSI`_ or `VirtIO performance`_. Additional configuration for configuring images in OpenStack can be found in the OpenStack Glance documentation. OpenStack Endpoints =================== For each OpenStack service three endpoints are created: ``admin``, ``internal`` and ``public``. .. code-block:: console ubuntu@ctl01:~$ openstack endpoint list --service keystone +----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------+ | ID | Region | Service Name | Service Type | Enabled | Interface | URL | +----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------+ | 008fec57922b4e9e8bf02c770039ae77 | RegionOne | keystone | identity | True | internal | http://172.16.10.26:5000/v3 | | 1a1f3c3340484bda9ef7e193f50599e6 | RegionOne | keystone | identity | True | admin | http://172.16.10.26:35357/v3 | | b0a47d42d0b6491b995d7e6230395de8 | RegionOne | keystone | identity | True | public | https://10.0.15.2:5000/v3 | +----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------+ MCP sets up all Openstack services to talk to each other over unencrypted connections on the internal management network. All admin/internal endpoints use plain http, while the public endpoints are https connections terminated via nginx at the ``VCP`` proxy VMs. To access the public endpoints an SSL certificate has to be provided. For convenience, the installation script will copy the required certificate to the ``cfg01`` node at ``/etc/ssl/certs/os_cacert``. Copy the certificate from the ``cfg01`` node to the client that will access the https endpoints and place it under ``/etc/ssl/certs/``. The SSL connection will be established automatically after. .. code-block:: console jenkins@jumpserver:~$ ssh -o StrictHostKeyChecking=no -i /var/lib/opnfv/mcp.rsa -l ubuntu 10.20.0.2 \ "cat /etc/ssl/certs/os_cacert" | sudo tee /etc/ssl/certs/os_cacert Reclass Model Viewer Tutorial ============================= In order to get a better understanding of the ``reclass`` model Fuel uses, the `reclass-doc`_ tool can be used to visualise the ``reclass`` model. To avoid installing packages on the ``jumpserver`` or another host, the ``cfg01`` Docker container can be used. Since the ``fuel`` git repository located on the ``jumpserver`` is already mounted inside ``cfg01`` container, the results can be visualized using a web browser on the ``jumpserver`` at the end of the procedure. .. code-block:: console jenkins@jumpserver:~$ docker exec -it fuel bash root@cfg01:~$ apt-get update root@cfg01:~$ apt-get install -y npm nodejs root@cfg01:~$ npm install -g reclass-doc root@cfg01:~$ ln -s /usr/bin/nodejs /usr/bin/node root@cfg01:~$ reclass-doc --output ~/fuel/mcp/reclass/modeler \ ~/fuel/mcp/reclass The generated documentation should be available on the ``jumpserver`` inside ``fuel`` git repo subpath ``mcp/reclass/modeler/index.html``. .. figure:: img/reclass_doc.png :width: 60% :align: center .. _fuel_userguide_references: References ========== #. :ref:`OPNFV Fuel Installation Instruction ` #. `Saltstack Documentation`_ #. `Saltstack Formulas`_ #. `VirtIO performance`_ #. `VirtIO SCSI`_ .. _`Saltstack Documentation`: https://docs.saltstack.com/en/latest/topics/ .. _`Saltstack Formulas`: https://salt-formulas.readthedocs.io/en/latest/ .. _`VirtIO performance`: https://mpolednik.github.io/2017/01/23/virtio-blk-vs-virtio-scsi/ .. _`VirtIO SCSI`: https://www.ovirt.org/develop/release-management/features/storage/virtio-scsi/ .. _`reclass-doc`: https://github.com/jirihybek/reclass-doc
