I recently encountered this error while trying to run one of my docker setups.
ERROR:formediawiki-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'
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”.
Just over a month ago I setup the Wikibase registry project on Wikimedia Cloud VPS using the docker-compose example provided by Wikibase docker images. The Wikibase registry is the first Wikibase install that I control that uses the Wikibase docker images, so I’ll be using it as an example showing how the docker images can be manipulated to configure MediaWiki, Wikibase, and load custom extensions and skins.
Since the last blog post new wikibase image tags have been created (the ‘bundle’ tags) that include some extensions you might want to enable, as well a quickstatements image for the quickstatements service used on Wikidata written by Magnus Manske.
The aim of the registry is to act as a central point for details of public Wikibase installs hosted around the web. Data held about the installs currently includes the URL for the home page, Query frontend URL and SPARQL API endpoint URL (if a query service exists).
During the workshop an initial data set was added, and this can be easily seen using the timeline view of the query service and a query that is explained within this post.
While working on a new Mediawiki project, and trying to setup a Kubernetes cluster on Wikimedia Cloud VPS to run it on, I hit a couple of snags. These were mainly to do with ingress into the cluster through a single static IP address and some sort of load balancer, which is usually provided by your cloud provider. I faffed around with various NodePort things, custom load balancer setups and ingress configurations before finally getting to a solution that worked for me using ingress and a traefik load balancer.
Below you’ll find my walk through, which works on Wikimedia Cloud VPS. Cloud VPS is an openstack powered public cloud solution. The walkthrough should also work for any other VPS host or a bare metal setup with few or no alterations.
This is a belated post about the Wikibase docker images that I recently created for the Wikidata 5th birthday. You can find the various images on docker hub and matching Dockerfiles on github. These images combined allow you to quickly create docker containers for Wikibase backed by MySQL and with a SPARQL query service running alongside updating live from the Wikibase install.
