This is an application to allow you pull new docker images created from your CI scripts. When you modificy a latest or any other tag, Kubernetes needs some call to tell to your deployment that need to be restarted and pull the new downloaded image.

CI script

Make sure your CI script will call your auto deployment:

export AUTODEPLOY_URL="https://YOUR_NAMESPACE.auto.gnosisdev.com/services/YOUR_DEPLOYMENT_NAME_1,YOUR_DEPLOYMENT_NAME_2,[...]/rollout"
export AUTODEPLOY_TOKEN="Your can set this with `openssl rand -base64 32`"
export TRAVIS_BRANCH=master

curl -s --output /dev/null --write-out "%{http_code}" \
    -H "Content-Type: application/json" \
    -X POST \
    -d '{"token": "'$AUTODEPLOY_TOKEN'", "push_data": {"tag": "'$TRAVIS_BRANCH'" }}' \
    $AUTODEPLOY_URL
