Role Name

=========



sets up local hashi setup



Requirements

------------



homebrew 



How to use it

------------

* run role

* run the launchctl commands printed in the debug output during execution (use unload to stop service)

* open docker and set it up

* add `/usr/local/var/nomad` to the docker shared folders

* reboot to make sure DNS works

* things should resolve as `myapp.service.dc1.consul`

* consul gui: http://consul.service.dc1.consul:8500/

* nomad gui: http://nomad.service.dc1.consul:4646/

* fabio gui: http://fabio.service.dc1.consul:9998/

* due to nomad + mac docker limition.. view logs via `docker logs containername`

* see `hashiparty.sh` in role `files/` for a start stop script

* See notes in tips and tricks at bottom of page



Using with fabio

---------------

fabio http runs on port 9999... all your url prefixes will require 9999...

easiset thing to do is for any app.. `urlprefix-myapp.service.dc1.consul:9999/`   then you can use DNS for http proxying and stop guessing ports



Role Variables

--------------

see `defaults.yml`



Example Playbook

----------------

`ansible-playbook workstation.yml -K`  (a few steps sudo, but dont run all as sudo)



```



- hosts: workstation



  tasks: 

    - name: setup hashi stack

      include_role:

        name: mac-hashi-local-dev

```



Example Nomad Job

----------------

running is as easy as

`nomad run jenkins.nomad`



jenkins.nomad

```

job "jenkins" {

  meta {

  	version = "20180515-02"

  }

  datacenters = ["dc1"]

  type = "service"

  update {

    max_parallel = 1

    min_healthy_time = "10s"

    healthy_deadline = "8m"

    auto_revert = false

    canary = 0

  }

  group "jenkins" {

    count = 1

    restart {

      attempts = 10

      interval = "5m"

      delay = "25s"

      mode = "delay"

    }

    task "jenkins" {

      driver = "docker"

      env {

        JENKINS_HOME = "/var/jenkins_home"

        HUDSON_HOME = "/var/jenkins_home"

     }

      config {

        image = "tomcat"

        force_pull = true

        port_map {

          jenkins_http = 8080

          jenkins-jlnp = 35123

        }

        volumes = [ 

        "local:/usr/local/tomcat/webapps"

	]

    #    args = [ "jenkins", "-dataclean","-config", "${NOMAD_TASK_DIR}/config.json" ]

      }

      resources {

        cpu    = 2000 # 500 MHz

        memory = 800 # 256MB

        network {

          mbits = 20

          port "jenkins_http" {}

          port "jenkins_jnlp" {

            static = "35123"

          }

        }

      }

      artifact {

        source      = "http://mirrors.jenkins.io/war-stable/latest/jenkins.war"

        destination = "local/"

      }

      service {

        name = "jenkins"

        tags = ["urlprefix-jenkins.service.dc1.consul:9999/"]

        port = "jenkins_http"

        check {

          name     = "alive"

          type     = "tcp"

          interval = "10s"

          timeout  = "2s"

        }

      }

#      service {

#        name = "jenkins-jnlp"

#        tags = ["jenkins"]

#        port = "jenkins_jnlp"

#        check {

#          name     = "alive"

#          type     = "tcp"

#          interval = "10s"

#          timeout  = "2s"

#        }

#      }

    }

  }

}

## Tips and Tricks ##



### nomad customization ###



Basic config defaults are provided at command line execution, but addtional nomad json configurations can be placed in `/usr/local/var/nomad/config`.



### OSXKEYCHAIN GOTCHA ###



you will probably need to remove the following line from `$HOME/.docker/config.json`

```

 "credSstore" : "osxkeychain",

```

or find the nomad fix and let me know!   In the meantime, nomad has a a config.json file pointing to config.json for docker auth
