CLI Tooling
Overview
The apb CLI tool helps Ansible Playbook Bundle (APB) authors create, build,
and publish their APBs to container registries. It enforces best practices and
takes care of the details so they should be easy to deploy.
Installing the Tool
Prerequisites
Access Permissions
You must be logged in via oc as a user with cluster-admin permissions:
To add this role to another user, you can run the following as a user that already has such permissions (for example, the system:admin default system user):
$ oc process -f openshift-permissions.template.yaml \ -p BROKeR_NAMeSPACe=openshift-ansible-service-broker \ -p GLOBAL_IMAGe_PROJeCT=default \ [-p USeR=<your_desired_user>] \ (1) | oc create -f -
This permission requirement is so that the development lifecycle of the apb
tool can function.
Installing via RPM
The APB CLI tool is provided by the apb package, which is available from the
rhel-7-server-ose-3.7-rpms channel:
$ sudo yum install apb
Verifying the Installation
Run apb help to make sure the tool is installed correctly:
$ apb help
usage: apb [-h] [--debug] [--project BASe_PATH]
{init,help,prepare,push,bootstrap,list,remove,build} ...
APB tooling for assisting in building and packaging APBs.
optional arguments:
-h, --help show this help message and exit
--debug enable debug output
--project BASe_PATH, -p BASe_PATH
Specify a path to your project. Defaults to CWD.
subcommand:
{init,help,prepare,push,bootstrap,list,remove,build}
init Initialize the directory for APB development
help Display this help message
prepare Prepare an ansible-container project for APB packaging
push Push local APB spec to an OAB
bootstrap Tell OAB to reload APBs from the
container repository
list List APBs from the target OAB
remove Remove APBs from the target OAB
build Build and package APB container
Typical Workflows
Local Registry
In order to use the OpenShift Container Registry to source APBs, you must have
configured the OpenShift Ansible broker to use the local_openshift type
registry adapter. See the
config
section for more information.
$ apb init my-new-apb $ cd my-new-apb $ apb build $ apb push --openshift $ apb list
If you are using a namespace other than the default openshift namespace to
host your APBs, then you can use the following command:
$ apb push -o --namespace <namespace>
Remote Registry
OAB can also be
configured
to use a remote registry and organization such as
docker.io/ansibleplaybookbundle
or your own personal account. In order to use this for developing APBs, you can
build and push to your remote registry and then bootstrap to reload your APBs:
$ apb init my-new-apb $ cd my-new-apb $ apb build --tag docker.io/my-org/my-new-apb $ docker push docker.io/my-org/my-new-apb $ apb bootstrap $ apb list
APB Creation Commands
init
Description
Initializes a directory structure for a new APB. Also creates example files for the new APB with sensible defaults.
Usage
$ apb init [OPTIONS] NAMe
Arguments
NAMe: Name of the APB and directory to be created.
Options
| Option, Shorthand | Description |
|---|---|
|
Show help message |
|
Force re-init and overwrite the directory |
|
Specify asynchronous operation on application. Usually defaulted to |
|
Generate an application with bindable settings |
|
Do not generate provision playbook and role |
|
Do not generate deprovision playbook and role |
|
Do not generate bind playbook and role |
|
Do not generate unbind playbook and role |
|
Do not generate any roles |
examples
Create directory my-new-apb:
$ apb init my-new-apb # my-new-apb/ # ├── apb.yml # ├── Dockerfile # ├── playbooks # │ ├── deprovision.yml # │ └── provision.yml # └── roles # ├── deprovision-my-new-apb # │ └── tasks # │ └── main.yml # └── provision-my-new-apb # └── tasks # └── main.yml
Create directory my-new-apb, but skip generating deprovision playbook and roles:
$ apb init my-new-apb --skip-deprovision # my-new-apb/ # ├── apb.yml # ├── Dockerfile # ├── playbooks # │ └── provision.yml # └── roles # └── provision-my-new-apb # └── tasks # └── main.yml
Create directory my-new-apb, overwriting any old versions. The APB will be configured to be bindable and require async:
$ apb init my-new-apb --force --bindable --async required # my-new-apb/ # ├── apb.yml # ├── Dockerfile # ├── playbooks # │ ├── bind.yml # │ ├── deprovision.yml # │ ├── provision.yml # │ └── unbind.yml # └── roles # ├── bind-my-new-apb # │ └── tasks # │ └── main.yml # ├── deprovision-my-new-apb # │ └── tasks # │ └── main.yml # ├── provision-my-new-apb # │ └── tasks # │ └── main.yml # └── unbind-my-new-apb # └── tasks # └── main.yml
prepare
Description
Compiles the APB into base64 encoding and writes it as a label to the Dockerfile.
This will allow the OAB to read the APB metadata from the registry without
downloading the images. This command must be run from inside the APB directory.
Running the build command will automatically run prepare as well, meaning you
generally do not need to run prepare by itself.
Usage
$ apb prepare [OPTIONS]
Options
| Option, Shorthand | Description |
|---|---|
|
Show help message |
|
Writes the APB spec to the target file name instead of a file named Dockerfile |
examples
Writes the label for the spec field in the Dockerfile:
$ apb prepare
Writes the label for the spec field in Dockerfile-custom:
$ apb prepare --dockerfile Dockerfile-custom
build
Description
Builds the image for the APB.
Similar to running apb prepare and docker build with a tag.
Usage
$ apb build [OPTIONS]
Options
| Option, Shorthand | Description |
|---|---|
|
Show help message |
|
Sets the tag of the built image to a string in the format |
|
Registry portion of the tag of the image (e.g., |
|
User or organization portion of the tag of the image |
examples
Build the image and use the name field from apb.yml as the tag:
$ apb build
Build the image and use the tag docker.io/my-org/my-new-apb:
$ apb build --tag docker.io/my-org/my-new-apb
Build the image and use the tag docker.io/my-org/<my-apb-name>:
$ apb build --registry docker.io --org my-org
Build the image using the file Dockerfile-custom as the Dockerfile definition:
$ apb build --dockerfile Dockerfile-custom
push
Description
Uploads the APB to an OpenShift Container Registry or a broker mock registry where it will be read by the OAB.
When using the broker’s mock registry, the spec is uploaded and will be
displayed in OpenShift Container Platform, but OpenShift Container Platform will pull the image from the
registry normally. Usually that means the registry where oc cluster up was
performed.
When using the OpenShift Container Registry, the image is uploaded to OpenShift Container Platform directly.
