# 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
```
