Download this Image

The image is available on cgr.dev:

docker pull cgr.dev/chainguard/mailpit:latest

Deploy this Image

You can deploy via Helm using the jouve Helm Chart, which is maintained by a mailpit user.

For compatibility with Chainguard Images, the values.yaml should look like this:

image:
  registry: cgr.dev
  repository: <your-repo>/mailpit
  tag: <tag>
  digest: <digest>

and you can deploy the Helm chart with:

helm repo add jouve https://jouve.github.io/charts/
helm install mailpit jouve/mailpit -f values.yaml

Send a Test Email

These instructions are based on upstream docs.

Once you've deployed mailpit to Kubernetes via Helm, as described above, you can try to send a test email.

Create a text file email.txt with the following contents:

From: sender@example.com
To: recipient@example.com
Subject: Email Subject

This is the body of the email.
It can contain multiple lines of text.

Port forward the mailpit service:

kubectl port-forward svc/mailpit-http 8025:80

In a separate terminal, port forward the SMTP server:

kubectl port-forward svc/mailpit-smtp 1025:25

In a separate terminal, send the email:

mailpit sendmail < email.txt

If you navigate to http://localhost:8025 you should see the email appear in the Mailpit UI.
