DevOps Velocity plugin installations on air-gapped networks

HCL DevOps Velocity (Velocity) plugin installations on air-gapped networks.

About this task

The installation instructions describe installing plugins in an air-gapped network that is physically isolated from unsecured networks.

Procedure

Pull the image from DockerHub on a machine that is not air-gapped, and save as a tarball to move to the air-gapped machine.
For example, use the following commands:
```
     docker pull urbancode/ucv-ext-github
     docker save -o github.tar urbancode/ucv-ext-github
     
```

Move *.tar to machine with access to the internal Docker registry.

For example, use the following commands:


     docker load -i github.tar
     docker tag urbancode/ucv-ext-github <internal-docker-registry>/ucv-ext-github
     docker push <internal-docker-registry>/ucv-ext-github

Update the Velocity instance with the new docker registry URL.
Note: You can use either of the following:
- The
```
<internal-docker-registry>
```
  prefix when referring to the image name.
- Set the
```
PRIVATE_DOCKER_REGISTRY_PREFIX
```
  environment variable in reporting-consumer.
If you changed the environment variable, you may need to restart the reporting-consumer container/pod. A restart of Velocity is not required.
The plugins tab will only display plugins that are installed from the private docker registry versus uninstalled plugins available from the private docker registry.
