Pushwagner

[X] Release early, [ ] Release often

Document config

Pushwagner searches for a config in: ./deploy.yml, ./.pw.yml, and ./config/deploy.yml.

Pushwagner is currently extremely opinionated to my usual practises.

Some conventions:

• Prefer ssh key-based deployment (Use reallly strong SSH-keys with your own ssh-agent or not at your own peril)
• Place most shit in /var/www|lib|keke/, logs in /var/log, cfg in /etc/.
• Let your app orchestration service or dscm set up access to deployers (I use salt|ansible|puppet for both app orchestration and dscm/infrastructure cfg) f.x.: NOPASSWD sudo service svcname <start|restart|stop>
• I usually separate application infrastructrure config (in infrastructure/app orchestration) and app config (toggles, etc)
• I usually thus create service wrappers / systemd / upstart shit with said dscm

Minimal configuration

# Must set a default path for file uploads
path_prefix: /var/apps

# Must specify a default environment.
environments:
  default:
    hosts: [test.example.com]

Environments

path_prefix: /var/apps

# Must specify a default environment.
environments:
  test: &test
    hosts: [test.example.com]
    user: testuser
  production: &production
    hosts: [a1.example.com, a2.example.com]
    user: productionuser
  default: 
    <<: *production

Maven (M2) repo integration

# required
path_prefix: /var/apps

maven:
  repositories:
    releases:  http://repo.example.com/nexus/content/repositories/releases
    snapshots: http://repo.example.com/nexus/content/repositories/snapshots
  artifacts:
    # creates /var/apps/foo/foo-webapp.jar by default (assumes foo-webapp is a jar)
    # I guess I should read the pom packaging some day... Or you can pull req it.
    foo:
      group_id:    com.example
      artifact_id: foo-webapp
      version:     1.0-SNAPSHOT

Static file uploads

path_prefix: /var/apps

static:
  /var/log/foo:
    - app.log
  static:
  	- file.txt
  	- folder/
  /usr/lib/foo:
    # Globbing support
  	- src/*{[!.git/]*}

        - /usr/sbin/service foo stop
      after:
        - /usr/sbin/service foo start

Environments

environments:
  test: &test
    hosts: [test.example.com]
