usage_description="
|
|
Adds the given SSH public key(s) to the currently authenticated GitLab account via the GitLab API
|
|
|
|
If no SSH public key is given, defaults to using ~/.ssh/id_rsa.pub
|
|
|
|
If a dash is given, reads the SSH public key(s) from standard input, ignoring comment lines so you can chain with tools like the adjacent scripts:
|
|
|
|
github_get_user_ssh_public_keys.sh
|
|
gitlab_get_user_ssh_public_keys.sh
|
|
github_get_ssh_public_keys.sh
|
|
gitlab_get_ssh_public_keys.sh
|
|
bitbucket_get_ssh_public_keys.sh
|
|
|
|
Will return a 400 error if the SSH public key is invalid or has already been added.
|
|
The script detects already existing keys and skips them to avoid this error
|
|
|
|
SSH Keys can be found in the Web UI here:
|
|
|
|
https://gitlab.com/profile/keys
|
|
|
|
If you get a 404 error it is likely that your \$GITLAB_TOKEN doesn't have the 'api' (full) permissions
|
|
You can regenerate a token with the right permissions here:
|
|
|
|
https://gitlab.com/profile/personal_access_tokens
|
|
|
|
Uses the adjacent script gitlab_api.sh, see there for authentication details
