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.
