The following are SMTP-related Rake tasks. ## Secrets GitLab can use SMTP configuration secrets to read from an encrypted file. The following Rake tasks are provided for updating the contents of the encrypted file. ### Show secret Show the contents of the current SMTP secrets. **Omnibus Installation** ```shell sudo gitlab-rake gitlab:smtp:secret:show ``` **Source Installation** ```shell bundle exec rake gitlab:smtp:secret:show RAILS_ENV=production ``` **Example output:** ```plaintext password: '123' user_name: 'gitlab-inst' ``` ### Edit secret Opens the secret contents in your editor, and writes the resulting content to the encrypted secret file when you exit. **Omnibus Installation** ```shell sudo gitlab-rake gitlab:smtp:secret:edit EDITOR=vim ``` **Source Installation** ```shell bundle exec rake gitlab:smtp:secret:edit RAILS_ENV=production EDITOR=vim ``` ### Write raw secret Write new secret content by providing it on `STDIN`. **Omnibus Installation** ```shell echo -e "password: '123'" | sudo gitlab-rake gitlab:smtp:secret:write ``` **Source Installation** ```shell echo -e "password: '123'" | bundle exec rake gitlab:smtp:secret:write RAILS_ENV=production ``` ### Secrets examples **Editor example** The write task can be used in cases where the edit command does not work with your editor: ```shell # Write the existing secret to a plaintext file sudo gitlab-rake gitlab:smtp:secret:show > smtp.yaml # Edit the smtp file in your editor ... # Re-encrypt the file cat smtp.yaml | sudo gitlab-rake gitlab:smtp:secret:write # Remove the plaintext file rm smtp.yaml ``` **KMS integration example** It can also be used as a receiving application for content encrypted with a KMS: ```shell gcloud kms decrypt --key my-key --keyring my-test-kms --plaintext-file=- --ciphertext-file=my-file --location=us-west1 | sudo gitlab-rake gitlab:smtp:secret:write ``` **Google Cloud secret integration example** It can also be used as a receiving application for secrets out of Google Cloud: ```shell gcloud secrets versions access latest --secret="my-test-secret" > $1 | sudo gitlab-rake gitlab:smtp:secret:write ```
