More support for variable substitution in tasks.json #163483
Description
There is current support for variable substitution in tasks.json, however it is limited to command, args, and options. It would be great to use this in other places throughout the tasks.json file.
Our team hit this when trying to use variable substitution in the docker-run task. We wanted to use the git branch name as the image tag and our work around was using find and replace.
ex:
{
"type": "docker-run",
"label": "docker-run: debug",
"dependsOn": ["docker-build"],
"python": {
"file": "path_to/app_entry_point.py"
},
"dockerRun": {
"image": "someregistry.io/someimage:${BRANCH}"
}
}
