Deploy release with Travis CI

The objective of this tutorial is to set up Travis Ci in order to deploy release into Github and DockerHub

• Prerequisites
• Deploy Github release via personal OAuth Token
• Deploy Docker image to docker hub

Prerequisites

• Travis CI account
• DockerHub account
• Github account
• Install Ruby https://guides.rubygems.org/rubygems-basics/

Deploy Github release via personal OAuth Token

Create an OAuth Token

Go here and create new one.

Make sure you have at least those permissions below:

Encrypt the Github

Go where your .travis.yaml is located.

Install travis tools

gem install travis

Copy your token generated previously and substitute $YOUR_TOKEN with it.

travis encrypt GITHUB_TOKEN=$YOUR_TOKEN --add

This command above encrypt your token and add the encrypted key into your .travis.yaml;

env:
  global:
    secure: sOQ51G...

Next you can use the variable $GITHUB_TOKEN in the .travis.yaml to set the api_key.

deploy:
  provider: releases
  api_key: $GITHUB_TOKEN
  file: dist/*
  skip_cleanup: true
  on:
    tags: true

Then create a tag an push it:

git tag -a v0.0.1 -m "Release version v0.0.1"
git push --tags

Travis will automatically trigger a new build and deploy it.

Finally go to https://github.com/$GITHUB_USERNAME/$GIT_REPO/releases. You can see you package released !

Deploy Docker image to docker hub

Create encrypted variables $DOCKER_USER and DOCKER_PASSWORD

Go where your .travis.yaml is located.

Install travis tools

gem install travis

substitute username and password by your docker hub credentials.

travis encrypt DOCKER_USER=username --add
travis encrypt DOCKER_PASS=password --add

This command above encrypt your token and add the encrypted key into your .travis.yaml;

env:
  global:
    secure: sOQ51G...
    secure: qiQR2A...

Next you can use the variable $DOCKER_USER and DOCKER_PASSWORD in the .travis.yaml.

Setup .travis.yaml

services:
- docker

script:
- export TAG=`if [ "$TRAVIS_BRANCH" == "master" ]; then echo "latest"; else echo $TRAVIS_BRANCH;
  fi`
- docker build -t $REPO:$TAG .
after_success:
- docker login -u $DOCKER_USER -p $DOCKER_PASSWORD
- docker tag $REPO:$COMMIT $REPO:$TAG
- docker tag $REPO:$COMMIT $REPO:$TRAVIS_BUILD_NUMBER
- docker push $REPO

env:
  global:
  - secure: B8Z5pvFYnGMQR...
  - secure: hmVbuNH4Z....
  - COMMIT=${TRAVIS_COMMIT::8}
  - REPO=$DOCKER_USER/chrono
