Doing this to get the latest release version from the Docker Compose git repo gets the latest version without a v prefix in the release tag, but I need the v prefix to be included if the release tag contains it.
COMPOSE_VERSION=`git ls-remote https://github.com/docker/compose | grep refs/tags | grep -oE "[0-9]+\.[0-9][0-9]+\.[0-9]+$" | sort --version-sort | tail -n 1`
echo $COMPOSE_VERSION
2.14.2 # desired: v2.14.2
I intent to use COMPOSE_VERSION to construct the download link for the release, so its important to have the v prefix if its found in the release tag.
sh -c "curl -L https://github.com/docker/compose/releases/download/${COMPOSE_VERSION}/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose"
Can the grep command for COMPOSE_VERSION be modified to achieve this?
Output of git ls-remote https://github.com/docker/compose | grep refs/tags
