Make a script at .travis/docker_push:
#!/bin/bash
echo "$DOCKER_PASSWORD" | docker login -u $DOCKER_USERNAME --password-stdin
if [ ! -z "${TRAVIS_TAG}" ]; then
docker tag edxops/MY_REPO:latest edxops/MY_REPO:${TRAVIS_TAG}
docker push edxops/MY_REPO:${TRAVIS_TAG}
fi
docker push edxops/MY_REPO:latest
In the travis UI, set the travis environment variables for DOCKER_USERNAME and DOCKER_PASSWORD
You cannot encrypt these and put them in .travis.yml at the time of this writing, the travis 'script' provider fails and writes the encrypted password to the console.
Add the following provider to your .travis.yml
- provider: script
on:
branch: master
tags: true
script: DOCKER_USERNAME=$DOCKER_USERNAME DOCKER_PASSWORD=$DOCKER_PASSWORD TRAVIS_TAG=$TRAVIS_TAG bash .travis/docker_push
If you need help configuring it for multiple providers look at the syntax here:
