Pipelines

Many Pipelines operations can be performed via the CLI, which requires the Pipelines plugin for the Heroku Toolbelt. To install:

% heroku plugins:install heroku-pipelines
% heroku help pipelines

% heroku apps:create une-pipe-staging
% git remote add staging [email protected]:une-pipe-staging.git
% config:set RACK_ENV=staging -r staging
% heroku config -r staging

% heroku apps:create une-pipe-production
% git remote add production [email protected]:une-pipe-production.git
% heroku config:set RACK_ENV=production -r production
% heroku config -r production

% heroku pipelines:create -a pipeline-name
% heroku pipelines:add -a app-name-staging pipleline-name
? Stage of app-name-staging: staging
Adding app-name-staging to pipeline-name pipeline as staging... done

// To deploy to production:
% heroku pipelines:promote -r staging
Fetching app info... done
Fetching apps from nest-pas-une-pipe... done

Une-Pipe-Production: succeeded

Github Sync and Reviews

Heroku, when connected to GitHub, can be configured to automatically or manually create development-stage apps in the pipeline. It will track a PR and keep the app updated as you commit to that branch and fire a rebuild.

review ---> staging ---> prod

On Heroku app dashboard:

Under deploy/ select the Github tab
Connect to Github repo
There is an option to automatic deploys
Under Review apps section, enable that option
Select option to Create new review apps for new pull requests automatically
