This is a simple way to install mailhog, might not be the best solution for everyone, you can look for repositories, still have to register the binary in the PATH, among other things, this is a manual simple install.

Binary download

Download mailhog from the releases page on github: https://github.com/mailhog/MailHog/releases Save the binary at /opt/mailhog/mailhog Give it executable permission chmod +x /opt/mailhog/mailhog

Init script

Download the gist: https://gist.github.com/renatomefi/d133fea9cb5a7b00f91edb24b83d9a31#file-init-d-mailhog-sh Put it at /etc/init.d/mailhog

Let's update from 3.8 to 3.9

FROM alpine:3.9

RUN addgroup -g 1000 app \
    && adduser -u 1000 -D -G app app

Build it again

renatomefi

Let's first build and run our newly image with a sleep time, thus pytest will have time to execute the test in it, no worries, this won't be the final solution

$ docker build -t alpine-app .
$ docker run --rm -d alpine-app sleep 60

We want now to copy the running container ID, and let's put it in the Testinfra command so it knows what container we want to test

./Dockerfile

FROM alpine:3.8

RUN addgroup -g 1000 app \
    && adduser -u 1000 -D -G app app

renatomefi

$ docker build -t alpine-app -f - . <<Dockerfile
