1. Multi-stage build with an extensive cleanup of useless files and optional image compression
2. Start three-node etcd cluster
3. Start three-node Patroni cluster
4. One container with haproxy
5. All container names are prefixed with "demo-" and don't have suffixes
6. Decommission dev_patroni_cluster.sh script, docker-compose is now standard de-facto.
7. Provide more examples in the docker/README.md
starting from 9.6 we need wal_level = 'replica' which is alias for 'hot_standby'. It was working before without problems, but if somebody change wal_level to replica, Patroni will expose pending_restart flag, although restart in this case is not necessary.
* bump versions of consul and etcd to the latest for travis integration-tests
For starting up cluster easy with docker-compose.
And unify Dockerfile and scripts to be able to work with docker-compose
and the old one dev_patroni_cluster.sh script
As the Dockerfile is there mainly to support developers, we want to build the Dockerfile using the current working
directory instead of a previously released version.
To help in developing features, the Dockerfile and its entrypoint have been extended.
The README.md explains stuff in detail, in short:
- you can now run a Patroni cluster with a single command
Due to the renaming of Governor to Patroni some old references needed to be updated.
Also some python packages need to be added.
Added entrypoint.sh as a script, to ensure Patroni will have PID = 1 when the container is run.
The Dockerfile now only builds upon the publicly available Ubuntu docker image, thereby reducing the size of the image.
etcd release 2.0.12 was released today as well, updated that dependency.
Removed aws reference from Dockerfile, remove unnecessary steps.
Connect using libpq parameters, therefore providing nice application name for Governor.
The StatusPage uses a BaseHTTPServer to server 3 simple http endpoints:
- pg_master, returns 200 if PostgreSQL is running as master
- pg_slave, returns 200 if PostgreSQL is running as slave
- pg_status, returns some information about the cluster
It does this by relying on the PostgreSQL connection of the Governor.
