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 docker-002 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.
Maintenance tasks
Delete a pad
As no admin dashboard plugin is installed, there are two methods to delete a pad:
- Send manually a request to https://pad.wolfplex.be/api/1/deletePad?apikey=APIKEY&padID=PADTODELETE
- Use the rOPS: roles/paas-docker/wrappers/files/pad-delete.py script fo send the request:
ssh equatower pad-delete $PADTODELETE.
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_neat2
They are included in the nasqueron/etherpad image.
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/dataroot/wolfplex/secrets.json.
On the Docker engine, API key should be available at /srv/pad/APIKEY.txt
Both are provisioned from Vault:
Vault secrets migration.
This service have secrets. They should be properly migrated in Vault.
