1 year ago This looks like a great feature to add to rocker. I haven't used contexts much myself but they look powerful for other use cases and don't look to complicated for rocker to interact with.
Detecting the context and passing it through as well as being able to override it from the command line options would be a great capability to add to rocker.
Hello,
I have been able to use rocker to create a docker image for ROS development but the image is created in the default context. I generally use a different docker context due to using management tools and development tools.
There seems to be no way to direct the image to be created in a different context other than default.
I have changed the CLI docker context to the correct one prior to running the rocker command, I have also set the DOCKER_CONTEXT environment variable. Neither of these has any effect on where the image is created.
It would be ideal if rocker could detect the current context and create the images in that context.
