# SMTP Rake tasks **(FREE SELF)**
|
|
|
|
[Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/67802) in GitLab 14.2.
|
|
|
|
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
|
|
```
