fix: expand tilde in --env-file paths to user home directory by tensorworkerr · Pull Request #13510 · docker/compose

tensorworkerr · 2026-01-14T03:31:15Z

When using --env-file=/~.env, the tilde was not expanded to the user's home directory. Instead, it was treated as a literal character and resolved relative to the current working directory, resulting in errors like "couldn't find env file: /current/dir/~/.env".

This adds an ExpandUser function that expands ~ to the home directory before converting relative paths to absolute paths.
Fixes #13508

What I did
-Added ExpandUser() function in internal/paths/paths.go that expands a leading ~ to the user's home directory using os.UserHomeDir()
-Updated the env file path processing in cmd/compose/compose.go to call ExpandUser() before checking if paths are absolute
-Added unit tests for the new function covering various edge cases (empty string, ~ only, ~/.env, ~/subdir/.env, absolute paths, relative paths, tilde in middle of path, ~otheruser/... syntax)

internal/paths/paths.go

you can use paths.ExpandUser from compose-go

Updated as you suggested.

ndeloof · 2026-01-14T12:58:37Z

A better place to fix this is GetEnvFromFile in compose-go: relativePathsResolver already manages this for usage within a compose file as file attributes, would make sense to have this logic all in one place

When using --env-file=~/.env, the tilde was not expanded to the user's home directory. Instead, it was treated as a literal character and resolved relative to the current working directory, resulting in errors like "couldn't find env file: /current/dir/~/.env". This adds an ExpandUser function that expands ~ to the home directory before converting relative paths to absolute paths. Fixes docker#13508 Signed-off-by: tensorworker <tensorworker@proton.me>

@ndeloof I don't think this was a bug, and actually the correct behavior; expansion is handled by the shell, and does not happen if the value is prefixed by a =; you'll see the same for any tool, e.g. trying with git;

git --git-dir=~/go/src/github.com/docker/compose/.git describe
fatal: not a git repository: '~/go/src/github.com/docker/compose/.git'

git --git-dir ~/go/src/github.com/docker/compose/.git describe
v2.26.1-891-gb760afaf9

Bit concerned that this could be a sliding slope.

ndeloof · 2026-01-15T09:10:12Z

@thaJeztah yes I know shell is in charge for this, but as long as we support both space and equal flag values, need to get an homogeneous behavior. compose.yaml already offers this feature

thaJeztah · 2026-01-15T11:17:38Z

Yeah, the issue here would be that it's not homogeneous across the CLI; other commands will not expand these, so now docker <some command> --some-flag=~/foo won't work, but docker compose --some-flag=~/foo will.
