wikibase-docker, Mediawiki & Wikibase update

January 29, 2019 / / 2 Comments

Today on the Wikibase Community User Group Telegram chat I noticed some people discussing issues with upgrading Mediawiki and Wikibase using the docker images provided for Wikibase.

As the wikibase-registry is currently only running Mediawiki 1.30 I should probably update it to 1.31, which is the next long term stable release.

This blog post was written as I performed the update and is yet to be proofread, so expect some typos. I hope it can help those that were chatting on Telegram today.

Starting state

Documentation

There is a small amount of documentation in the wikibase docker image README file that talks about upgrading, but this simply tells you to run update.php.

Update.php has its own documentation on mediawiki.org.
None of this helps you piece everything together for the docker world.

Installation

The installation creation process is documented in this blog post, and some customization regarding LocalSettings and extensions was covered here.
The current state of the docker-compose file can be seen below with private details redacted.

This docker-compose files is found in /root/wikibase-registry on the server hosting the installation. (Yes I know that’s a dumb place, but that’s not the point of this post)

A firewall is blocking sharing between Windows and the containers – Docker

January 9, 2019 / / 1 Comment

I recently encountered this error while trying to run one of my docker setups.

ERROR: for mediawiki-docker-dev_db-slave_1  Cannot start service db-slave: b'OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/tmp/mwdd/entrypoint.sh\": stat /tmp/mwdd/entrypoint.sh: no such file or directory": unknown'
Code language: JavaScript (javascript)

I have encountered errors like this before and it has always ended up being related to docker and sharing my drives to the linux VM that actually runs my containers.

Checking the shared drives menu of the docker UI everything seemed to be fine.

However when removing the drive share and re sharing the drive I got an error message saying that there was a “Firewall detected” and that “A firewall is blocking file Sharing between Windows and the containers. See documentation for more info”.

The docs seem to suggest that my firewall rule had vanished somehow. I spent a few minutes digging around and tinkering with firewall rules before determining the rule itself was not the issue. The next suggestion was to “reinstall the File and Print sharing service on the Hyper-V virtual network card “

Opening PowerShell as administrator and running the commands suggested on stackoverflow (switching the DockerNAT network) seemed to do the trick.

Set-NetConnectionProfile -interfacealias "vEthernet (DockerNAT)" -NetworkCategory Private
Code language: JavaScript (javascript)

I still have no idea why this happened. Did I accidently set the DockerNAT network to be public? Could the Docker UI really not check the firewall rule itself and propose the fix?
