Allow rebuild container without cache

[rubensa]

Sometimes I have a Dockerfile that installs software downloaded form Internet. If download fails (cause a network failure or something), the image is build anyway.

The problem is that I can't force VSCode to rebuild the image (so, once the network issue is fixed, the software can be downloaded and installed) using Remote-Containers: Rebuild Container as it always uses cache.

Please provide a Remote-Containers: Rebuild Container without Cache, or similar command, containing the --no-cache option.

I too would like this feature. I sometimes have issues in nodejs where an issue with docker itselfs requires me to rebuild the entire image. But I can't. My only workaround is to change the source image from node:12 to node:11 and vice-versa. This should be either an option in .devcontainer.json or an entirely new command.

do an echo "something" run command when you want to rebuild, ugly, but useful

yes I think especially for devcontainers where we want always with the latest version the --no-chache option should be possible. I would be happy with a buildArgs in the devcontainer.json
Better to have the no-chache everytime (and pay this with some seconds startup time) than to have outdated stuff in the development environment.

Work around: copy the docker build command from the log, append --no-cache and run in a separate terminal, return to vscode and "Re-open in Container" to use the refreshed cache
(helpfully, the paths in the command appear to use absolute paths, so you can just copy-paste)

Is there any plan for this? After some time and issues i stumbled upon this issue and its frustrating that i can not truly rebuild/clean (with --no-cache). Manualy deleting an image only works sometimes but when you are working in a bigger context; this leads often to "delete all images because i dont now comfortably what layer is used by cache".

Maintainers, this sort of thing would be trivial if this extension was open-sourced, you'd get a PR in no time flat. Please consider open sourcing this extension!
