Shared between Nasqueron and Wolfplex

The same Etherpad installation is served at two domains:

Upgrade

The easiest way is to spin a new container.

You can also upgrade code in the live container, updating Git code then restarting Node.

Procedure A - upgrade container

First, pull new image and remove old container on Equatower:

$ docker pull nasqueron/etherpad
$ docker stop pad
$ docker rm pad
$ rm /srv/etherpad/.ok*

Then, on the Salt master, spin the new container:

$ cd /opt/salt/nasqueron-operations
$ salt equatower state.apply roles/paas-docker/containers/etherpad

If something weird happens after the update:

  • if you forget to remove /srv/etherpad/.ok-plugins, plugins won't be reinstalled
  • if you forget to remove /srv/etherpad/.ok-apikey, you'll get an API key issue (see below)
  • if you forget to remove /srv/etherpad/.ok-abiword, abiword won't be reinstalled

To use `rm /srv/etherpad/.ok*` on Equatower and then repplay the roles/paas-docker/containers/etherpad state works to fix the situation, as those three steps can be done when the container is live.

Procedure B - upgrade code

$ docker exec -it pad bash
$ git pull

Updating 2e81b39..45266f9

$ logout
$ docker restart pad 
$ docker logs pad 

[2016-08-25 00:40:24.711] [INFO] console - Your Etherpad version is 1.6.0 (45266f9)

Check the two versions match.

Note most recent code lives in the develop branch, not the master one.

Launch container

run-pad

Source script available at https://devcentral.nasqueron.org/P210.

Maintenance tasks

Delete a pad

As no admin dashboard plugin is installed, there are two methods to delete a pad:

In the past, the few delete pad requests occurred for privacy reasons. Privacy is an acceptable justification to delete a pad.

Repair

There are scripts to delete a pad or to repair a corrupted pad.

Those are documented at https://github.com/ether/etherpad-lite/wiki/Getting-to-know-the-tools-in-bin

Past known issues

Instability

When a copy/paste was done, server could crash.

This has been fixed by switching database to utf8mb4_bin:

ALTER DATABASE `etherpad` CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
ALTER TABLE `etherpad.store` CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;

Missing plugins

The installation requires two plugins, provided as npm packages:

  • ep_ether-o-meter
  • ep_author_neat

We now install them in run-pad:

PLUGINS="ep_ether-o-meter ep_author_neat"

for plugin in $PLUGINS; do
        docker exec $INSTANCE npm install $plugin
done

API key issue

http://www.wolfplex.be/pad/ could be empty. When that occurs, the API key on this site diverges from ours.

They store their API on Ysul at /var/wwwroot/wolfplex.be/.dat/secrets-api.json.

Normally, this is now handled by the following line from run-pad script: docker cp /data/etherpad/APIKEY.txt $INSTANCE:opt/etherpad-lite/APIKEY.txt

Vault secrets migration.

This service have secrets. They should be properly migrated in Vault.
