stolon-boshrelease

This release is WIP

This is a bosh release using postgres, stolon & consul to deploy postgres in a highly available manner.

Hints

• This release is dependant on consul-release (tested with version 170).

• This release can be deployed with consul-servers inclueded or without them by leveraging a different deployment which provide the consul_common and consul_client links.

• There are some ops- and vars-files included to deploy via bosh2

  • Deployment with external consul cluster:

    bosh2 -e bosh-lite -d stolon \
      deploy \
        --vars-file manifest/vars.default.yml \
      manifest/deployment.stolon.yml
    

  • Deployment with a consul cluster included:

    bosh2 -e bosh-lite -d stolon_consul
      deploy \
        --ops-file manifest/ops.include-consul.yml \
        --vars-file manifest/vars.default.yml \
        --vars-file manifest/vars.include-consul.yml \
      manifest/deployment.stolon.yml
    

  Some of the settings (consul_common_link_name, consul_deployment_name, ...) may need to be changed either by a vars-file or by specifying them via command line option like ... --var 'consul_deployment_name=this_is_my_consul_cluster' ....

• You can also spin up a separate consul server deployment which you can then use to link to the actual stolon deployment:

  bosh2 -e bosh-lite -d consul \
    deploy \
      --vars-file manifest/vars.include-consul.yml \
    manifest/deployment.consul.yml
  

TODOs

• More testing, smoketest, CI
• test with pg_rewind
• include some backup solution (wal-e, pgbackrest, barman, ...)
• loadbalance mutltiple proxies (?)

Attention

This is work in progress. This is first bosh release, more of a playground and should be treated as such ...you have been warned!
