apb

Getting Started

Create a namespace

Once logged into your OCP cluster, you must first create a project:

$ oc new-project test-project

Add a registry

First add the default registry (ansibleplaybookbundle on Dockerhub):

$ apb registry add docker

Or to add a custom registry:

$ apb registry add docker --org ansibleplaybookbundle --type dockerhub

Then you can list your registries:

$ apb registry list
Found registries already in config:                                   
 NAME       TYPE          ORG                       URL               
 ------ -+- --------- -+- --------------------- -+- ---------         
 docker  |  dockerhub  |  ansibleplaybookbundle  |  docker.io

List available APBs

Once a registry is configured, run apb bundle list:

$ apb bundle list
Found specs already in registry: [docker]                                                                                                    
 BUNDLE                    IMAGE                                                                   REGISTRY                                  
 --------------------- -+- ------------------------------------------------------------------- -+- --------

 pyzip-demo-db-apb      |  docker.io/ansibleplaybookbundle/pyzip-demo-db-apb:latest             |  docker

This command loads and caches APB specs (metadata) from newly added registries. Cached specs can be updated with apb bundle list --refresh

Provision an APB

Provision any of the listed APBs like so:

$ apb bundle provision <bundle_name> -n myproject --follow

To provision an APB with the admin ClusterRole used in the APB sandbox, run:

$ apb bundle provision <bundle_name> -n myproject --sandbox-role admin --follow

Note: the --follow flag waits for the APB to start running and shows logs on-screen.

Tips

Enabling tab completion for apb

apb supports command tab completion for bash and zsh:

$ source <(apb completion bash) # load bash completion into session
$ source <(apb completion zsh) # load zsh completion into session

Troubleshooting

Using apb with openshift.io

In the starter tier of openshift.io, the secret quota is 20 (at the time of this writing). Since each apb bundle provision action creates a serviceaccount with an API token residing in a secret, it's possible to hit this limit after a few provisions. Cleaning up bundle-*****-[..] serviceaccounts will help resolve this. You can check if you're hitting this limit with oc get quota object-counts -o yaml
