I am trying to solve a problem generating a snippet of markdown. I am using Eclipse JKube to build an image in which there are embedded release material and docs. I instruct users to run some commands to copy these resources locally:
From a shell enter this directory and run the appropriate command below.
For **Powershell**:
`($id = docker create ${jkube.docker.registry}/${dockerRepoPrefix}/${dkr_image_name}:${dkr_image_tag}); (docker cp "$($id):/usr/aws-build/." .); (docker rm -v $id)`
As you can see I am attempting to use Maven filtering so that different target registries and repos and tags all get correct instructions. Note: I need Markdown, not processed Markdown, as I need to supply that to different doc generators.
The problem is that for DockerHub the registry is empty resulting in something like:
From a shell enter this directory and run the appropriate command below.
For **Powershell**:
`($id = docker create /acme-hammers/banger:v0.8.9); (docker cp "$($id):/usr/aws-build/." .); (docker rm -v $id)`
^._ THE PROBLEM
That leading slash breaks it.
I cannot a solution using filtering or Maven properties. It needs some dynamic way to exclude the slash. For example if I were to use an aggregate property, the problem just moves there:
<properties>
...
<fullImgName>${jkube.docker.registry}/${dockerRepoPrefix}/${dkr_image_name}:${dkr_image_tag}</fullImgName>
...
</properties>
I also cannot just use the DockerHub registry explicitly like this:
($id = docker create registry.hub.docker.com/acme-hammers/banger:v0.8.9); (docker cp "$($id):/usr/aws-build/." .); (docker rm -v $id)
The image is not stored that way in the local Daemon (the registry is removed for DockerHub builds) and it fails to resolve.
Is there a good way, either with Maven filtering, or other, to optionally exclude the '/' when there is no registry specified, or when the DockerHub registry is supplied?
Alternatively is there a way to force JKube to always include the registry in the image name?
