docker run
environment variables file (--env-file) moby/moby#4174--label-file
weird behavior #838This error was originally introduced
ErrBadEnvVariable
in moby/moby@500c8ba, but merely for convenience, and not used as a sentinel error. After the code was moved from the daemon to the cli repository, it was renamed to be more genericErrBadKey
in commit 2b17f4c.A search on GitHub shows that there's no consumers using this error as sentinel error, and it's not used in our own code as such, so it should be safe to remove this error.
This patch removes the
ErrBadKey
error-type; it also removes the prefix (poorly formatted environment:
) to make the error more generic, because the same function was used both for env-files and label-files.- What I did
