Use it with the same -caution you would give any other pre-release software. - -**Most importantly** follow this one rule: don't re-run the entrypoint -playbook multiple times in a row without cleaning up after previous -runs if some of the CFME steps have ran. This is a known -flake. Cleanup instructions are provided at the bottom of this README. - - -# Usage - -This section describes the basic usage of this role. All parameters -will use their [default values](defaults/main.yml). - -## Pre-flight Checks - -**IMPORTANT:** As documented above in [the prerequisites](#prerequisites), - you **must already** have your OCP cluster up and running. - -**Optional:** The ManageIQ pod is fairly large (about 1.7 GB) so to -save some spin-up time post-deployment, you can begin pre-pulling the -docker image to each of your nodes now: - -``` -root@node0x # docker pull docker.io/manageiq/manageiq-pods:app-latest-fine -``` - -## Getting Started - -1) The *entry point playbook* to install CFME is located in -[the BYO playbooks](../../playbooks/byo/openshift-cfme/config.yml) -directory - -2) Update your existing `hosts` inventory file and ensure the -parameter `openshift_cfme_install_app` is set to `True` under the -`[OSEv3:vars]` block. - -2) Using your existing `hosts` inventory file, run `ansible-playbook` -with the entry point playbook: - -``` -$ ansible-playbook -v -i <INVENTORY_FILE> playbooks/byo/openshift-cfme/config.yml -``` - -## Next Steps - -Once complete, the playbook will let you know: - - -``` -TASK [openshift_cfme : Status update] ********************************************************* -ok: [ho.st.na.me] => { - "msg": "CFME has been deployed. Note that there will be a delay before it is fully initialized.\n" -} -``` - -This will take several minutes (*possibly 10 or more*, depending on -your network connection). However, you can get some insight into the -deployment process during initialization. - -### oc describe pod manageiq-0 - -*Some useful information about the output you will see if you run the -`oc describe pod manageiq-0` command* - -**Readiness probe**s - These will take a while to become -`Healthy`. The initial health probes won't even happen for at least 8 -minutes depending on how long it takes you to pull down the large -images. ManageIQ is a large application so it may take a considerable -amount of time for it to deploy and be marked as `Healthy`. - -If you go to the node you know the application is running on (check -for `Successfully assigned manageiq-0 to <HOST|IP>` in the `describe` -output) you can run a `docker pull` command to monitor the progress of -the image pull: - -``` -[root@cfme-node ~]# docker pull docker.io/manageiq/manageiq-pods:app-latest-fine -Trying to pull repository docker.io/manageiq/manageiq-pods ... -sha256:6c055ca9d3c65cd694d6c0e28986b5239ba56bbdf0488cccdaa283d545258f8a: Pulling from docker.io/manageiq/manageiq-pods -Digest: sha256:6c055ca9d3c65cd694d6c0e28986b5239ba56bbdf0488cccdaa283d545258f8a -Status: Image is up to date for docker.io/manageiq/manageiq-pods:app-latest-fine -``` - -The example above demonstrates the case where the image has been -successfully pulled already. - -If the image isn't completely pulled already then you will see -multiple progress bars detailing each image layer download status. - - -### rsh - -*Useful inspection/progress monitoring techniques with the `oc rsh` -command.* - - -On your master node, switch to the `cfme` project (or whatever you -named it if you overrode the `openshift_cfme_project` variable) and -check on the pod states: - -``` -[root@cfme-master01 ~]# oc project cfme -Now using project "cfme" on server "https://10.10.0.100:8443". - -[root@cfme-master01 ~]# oc get pod -NAME READY STATUS RESTARTS AGE -manageiq-0 0/1 Running 0 14m -memcached-1-3lk7g 1/1 Running 0 14m -postgresql-1-12slb 1/1 Running 0 14m -``` - -Note how the `manageiq-0` pod says `0/1` under the **READY** -column. After some time (depending on your network connection) you'll -be able to `rsh` into the pod to find out more of what's happening in -real time. First, the easy-mode command, run this once `rsh` is -available and then watch until it says `Started Initialize Appliance -Database`: - -``` -[root@cfme-master01 ~]# oc rsh manageiq-0 journalctl -f -u appliance-initialize.service -``` - -For the full explanation of what this means, and more interactive -inspection techniques, keep reading on. - -To obtain a shell on our `manageiq` pod we use this command: - -``` -[root@cfme-master01 ~]# oc rsh manageiq-0 bash -l -``` - -The `rsh` command opens a shell in your pod for you. In this case it's -the pod called `manageiq-0`. `systemd` is managing the services in -this pod so we can use the `list-units` command to see what is running -currently: `# systemctl list-units | grep appliance`. - -If you see the `appliance-initialize` service running, this indicates -that basic setup is still in progress. We can monitor the process with -the `journalctl` command like so: - - -``` -[root@manageiq-0 vmdb]# journalctl -f -u appliance-initialize.service -Jun 14 14:55:52 manageiq-0 appliance-initialize.sh[58]: == Checking deployment status == -Jun 14 14:55:52 manageiq-0 appliance-initialize.sh[58]: No pre-existing EVM configuration found on region PV -Jun 14 14:55:52 manageiq-0 appliance-initialize.sh[58]: == Checking for existing data on server PV == -Jun 14 14:55:52 manageiq-0 appliance-initialize.sh[58]: == Starting New Deployment == -Jun 14 14:55:52 manageiq-0 appliance-initialize.sh[58]: == Applying memcached config == -Jun 14 14:55:53 manageiq-0 appliance-initialize.sh[58]: == Initializing Appliance == -Jun 14 14:55:57 manageiq-0 appliance-initialize.sh[58]: create encryption key -Jun 14 14:55:57 manageiq-0 appliance-initialize.sh[58]: configuring external database -Jun 14 14:55:57 manageiq-0 appliance-initialize.sh[58]: Checking for connections to the database... -Jun 14 14:56:09 manageiq-0 appliance-initialize.sh[58]: Create region starting -Jun 14 14:58:15 manageiq-0 appliance-initialize.sh[58]: Create region complete -Jun 14 14:58:15 manageiq-0 appliance-initialize.sh[58]: == Initializing PV data == -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: == Initializing PV data backup == -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: sending incremental file list -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: created directory /persistent/server-deploy/backup/backup_2017_06_14_145816 -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/REGION -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/certs/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/certs/v2_key -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/config/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: region-data/var/www/miq/vmdb/config/database.yml -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/var/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/var/www/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/var/www/miq/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/var/www/miq/vmdb/ -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: server-data/var/www/miq/vmdb/GUID -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: sent 1330 bytes received 136 bytes 2932.00 bytes/sec -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: total size is 770 speedup is 0.53 -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: == Restoring PV data symlinks == -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: /var/www/miq/vmdb/REGION symlink is already in place, skipping -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: /var/www/miq/vmdb/config/database.yml symlink is already in place, skipping -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: /var/www/miq/vmdb/certs/v2_key symlink is already in place, skipping -Jun 14 14:58:16 manageiq-0 appliance-initialize.sh[58]: /var/www/miq/vmdb/log symlink is already in place, skipping -Jun 14 14:58:28 manageiq-0 systemctl[304]: Removed symlink /etc/systemd/system/multi-user.target.wants/appliance-initialize.service. -Jun 14 14:58:29 manageiq-0 systemd[1]: Started Initialize Appliance Database. -``` - -Most of what we see here (above) is the initial database seeding -process.
