问题
I can't manually log into my private GitLab Docker Registry from CLI:
# docker login -u "${DOCKER_USER}" -p "${DOCKER_PASS}" "${DOCKER_URL}"
error getting credentials - err: exit status 1, out: `Cannot autolaunch D-Bus without X11 $DISPLAY`
System info:
- Ubuntu 18.04
- docker-ce 18.03.1~ce~3-0~ubuntu (from official repo, without install script)
There is no ~/.docker/config.json for any users and I'm executing the docker login as root.
On Google, I just find recommendations to export DISPLAY... Can docker only login to remote registries in a GUI environment?
Exporting DISPLAY=0:0 yields:
error getting credentials - err: exit status 1, out: `Failed to execute child process “dbus-launch” (No such file or directory)`
Am I missing some dependency? Docker runs fine otherwise, but login doesn't work. I know there are backends to store credentials, but I don't want to store credentials. I'm just trying to authenticate against my registry to pull an image, doesn't that work in Docker ootb?
回答1:
The docker-compose package unnecessarily depend on the broken golang-github-docker-docker-credential-helpers package. Removing the executable fixes this.
rm /usr/bin/docker-credential-secretservice
Note: This is a workaround and will need to be repeated each time the package is updated.
This affects the Ubuntu 18.04 (and possibly other non-LTS releases) and some Debian releases.
