rethinkdb-snap

This is an 'external' snap of RethinkDB 2.3.5, meaning it downloads the source and builds it.

Building

On Ubuntu 16.04 LTS with snapcraft installed ('sudo apt install snapcraft'):

  git clone https://github.com/markshuttle/rethinkdb-snap
  cd rethinkdb-snap
  snapcraft

Installing

Installing the snap you built yourself means you are installing an unsigned snap, hence the --force-dangerous below. You will be able to install 'rethinkdb' directly from the store shortly, signed by the publisher.

  sudo snap install --force-dangerous ./rethinkdb_2.3.5_amd64.snap

Using it

The RethinkDB snap creates a 'default' database on installation. Configuration of that database is at:

  /var/snap/rethinkdb/common/config/default.conf

You can add additional configuration files 'foo.conf' in that same directory to get additional instances of RethinkDB. Don't set runuser, rungroup or any of the file path configuration items, those are opinionated in the snap because snaps are opinionated about data persistence :)

Snaps run sandboxed, so there is a modified launch script that is passed to the init system. That makes sure that data is in places that the snap can write. The default port for the web adminiistration interface is 28080:

  http://localhost:28080

RethinkDB starts on boot after the snap is installed. The launch script is bin/snap-launch.sh which is also executable as rethinkdb.launch after installation. RethinkDB itself is executable directly as rethinkdb.

Data for the instances managed by the snap service is stored in:

  /var/snap/rethinkdb/common/data/<instance>/

Feedback

I am sabdfl on Freenode, feedback to me directly or in #snappy on Freenode please.

If the snap proves useful I can rework this as a PR for RethinkDB itself, enabling snaps to be published automatically to the edge channel in the store from Travis hooks.
