Go sample app to use for new repos

This is a go sample repo. This was adapted from hydra.

This sample app will implement the following

• Basic web server handling /v1/details and /v1/status request
• This will communicate with Synq API
• DB Connection with flyway setup
• Tests with mocking
• CircleCI setup (with coveralls setup)
• Uses govendor to vendor/ management

This workspace works! You can check out the test by running

circleci build

If you want to run it locally, you need to setup the test database

createuser -U <postgres admin> -h localhost -P -d circleci
createdb -U circleci -h localhost gosample_test
cd sql/environments/test && flyway migrate

Setting up Cirlce CI

When you copy the workspace the first thing you should do is setup circleci and coveralls. This is fairly straightforward.

• Go to CircleCI Dashboard
• Add Project
• Setup Project the workspace you are working on
• Starting Building (assuming you select 2.0)
• Go to Settings and then Status Badges and copy the badge to your README.md
  • If its a private workspace, you need to setup an API Token in API Permissions

Setting up Coveralls

• Go to Add Repos to add your repo
• Find your repo (you may need to hit the Synq Repos button on the upper right)
• Click it "On"
• Go to Details and copy the repo token
• Go to CircleCI's ENV settings and create the ENV VAR COVERALLS_TOKEN using the copied repo token.
• Copy the Coveralls Badge and paste it into your README.md
• Once yuou have some tests, go to the coveralls Settings page and change the Coverage Threshold to minimum 75% and Decrease threshold to 5%

Setup your GitHub "protected" branch

• Go to GitHub repo settings and branches
• Make master a protected branch
• Check Project Branch, Require status checks to pass before merging and make sure ci/circleci is required. Save your changes
  • Note, coveralls won't show until you've ran a successful build with it so you can come back to make that required as well

Things to change before you start using it

• Go to .circleci/config.yml and
  • replace gosample_test with the database you want
  • replace gosample with the name of your workspace
• Go to sql/environments/test/flywayconf
  • replace gosample_test with database you want
• Change the sql/migrations/V000__Init.sql with the table you want
• And of course, change the code as needed, but this workspace starts at 100% code coverage so try to maintain high coverage!
