This is an unofficial very small Dockerfile image (~34 MB uncompressed) for mailcatcher gem. It is based on Alpine Linux and using the last available release from the official Github repo of mailcatcher.
The difference between this image and most of the other ones that the port numbers are envinronment varibales. You can change them to suit your needs.
Here is an example on how your docker-compose file should look
ports:
- "1080:1080"
- "1025:1025"
environment:
- HTTP_PORT=1080
- SMTP_PORT=1025Get it:
docker pull thedartsco/mailcatcher
Run it:
docker run -d -p 1080:1080 --name mailcatcher thedartsco/mailcatcher
Link it:
docker run -d --link mailcatcher -e SMTP_HOST=mailcatcher --name php56 thedartsco/php:5.6
Then you can send emails from your app and check out the web interface: http://<your docker host\>:1080/.
If you want to send emails from your host you can map the 1025 port:
docker run -d -p 1080:1080 -p 1025:1025 --name mail thedartsco/mailcatcher
then send yout emails through your docker host on port 1025 (or any port you want)
Just clone this repo and run:
docker build -t thedartsco/mailcatcher .
