@Yash4357 most likely permissions issues on the SQLite database. Can you copy/paste your .env and docker-compose.override.yml files here please?

.env:
MW_DOCKER_PORT=8080
MW_SCRIPT_PATH=/w
MW_SERVER=http://localhost:8080
MEDIAWIKI_USER=Admin
MEDIAWIKI_PASSWORD=dockerpass

Thanks. So, no docker-compose.override.yml file, is that right?

And what version of Docker for Windows are you using?

Yes, there is no docker-compose.override.yml file,
And I am using docker version:19.03.13

How did you install Docker? Can you check the file permissions on the cache directory and make sure it's readable by your user?

Do I have to check cache directory of mediawiki?

I have install docker-desktop

I have used host.docker.internal but it is showing site can't be reached

I have tried again via host.docker.internal. It give same error.

host.docker.internal is if you have some need for accessing your host from within the container. If you want to access your MediaWiki site via the browser from your host, you'd use http://localhost:8080 (on Linux or macOS). I'm not sure about the details of Docker for Windows.

Please double check the permissions on the cache directory in the root of the MediaWiki repository, especially the SQLite file(s) inside of it.

Is this ok?

Can anyone tell me now, how I can resolve this error?

@Yash4357 Have you tried the re-install directions here? There could be a problem with your LocalSettings file that could cause this.

I have re-install this two times, then also it is not working.

Sorry that did not help. I think many people (including myself) are currently on vacation, so you might not get more responses until after the new year.

What are the values of $wgDBserver and $wgDBuser in LocalSettings.php? Is $wgDBpassword in LocalSettings.php non-empty?

Database settings:

$wgDBtype = "sqlite";
$wgDBserver = "";
$wgDBname = "my_wiki";
$wgDBuser = "";
$wgDBpassword = "";

This is are the settings.

To be sure: That means all the $wgDBserver, $wgDBuser and $wgDBpassword settings are entirely unset and empty?

Also, what exactly are $wgScriptPath and $wgSQLiteDataDir set to?

$wgSQLiteDataDir = "/var/www/html/w/cache/sqlite";

$wgScriptPath = "/w";

Could you please answer all questions? Thanks. :)

$wgDBserver, $wgDBuser and $wgDBpassword settings are entirely unset and empty.

And $wgScriptPath and $wgSQLiteDataDir set to path as I mentioned above.

$wgDBserver, $wgDBuser and $wgDBpassword settings are entirely unset and empty.

T248359 came to my mind...

I had this exact error when installing MediaWiki-Docker on Windows a month ago. It seems the cache/sqlite directory isn't readable by the MediaWiki inside the MediaWiki Docker container (chmod o+rwx cache/sqlite fixed it)

This was the list of permissions for the directories just after install:

It sounds like the GID/UID override is needed for windows too (T273218: Update documentation to specify UID/GID override for macOS)

Adding to what @Soda mentioned above:

On the current master branch (1.39), I can consistently reproduce the same problem on Windows no matter how many times I reinstalled the database.
Upon some investigations, I find that there are permission issues with the cache/sqlite folder, changing the permission resolved the issue.

Change 836200 had a related patch set uploaded (by Alistair3149; author: Alistair3149):

[mediawiki/core@master] Add Windows-specific instructions in DEVELOPERS.md

https://gerrit.wikimedia.org/r/836200

Shouldn't a Dockerfile be modified to run chmod o+rwx cache/sqlite so the user doesn't run into this error every time and then be required to run it?

I don't know how to do that so I just added the documentation so that people with Windows setup will be able to use the docker environment for MW development. If someone knows how to implement it in the dockerfile, please feel free to amend this patch or submit another one and I will close this one.

@Legoktm any help with doing this? I think https://github.com/wikimedia/mediawiki-docker/blob/master/Dockerfile-alpine.template needs to be modified.

Change 836200 merged by jenkins-bot:

[mediawiki/core@master] Add Windows-specific instructions in DEVELOPERS.md

https://gerrit.wikimedia.org/r/836200

I downloaded the docker-compose.yml from https://github.com/wikimedia/mediawiki/blob/master/docker-compose.yml and I'm trying to modify it to upgrade my existing wikimedia website. First of all, I need to make it work in my local PC and be able to browse the site with the latest (wikimedia/php/apache) versions. The URL should be simple such as http://localhost:8080 So far I did not make it work.

Can someone explain below section of the docker-compose.yml file? Does "/var/www/html/w" mean it will install MW to W: drive?
By policy I'm not allowed to map a new drive at office. Thus I only have access to C: drive. If that's the case, how should I modify this docker compose yaml file?

volumes:

• ./:/var/www/html/w:cached env_file:
• '.env' environment: MW_LOG_DIR: /var/www/html/w/cache MW_INSTALL_PATH: /var/www/html/w

Much appreciated!

@Hyang26: Hi and welcome! Please ask general support questions in support forums instead, as your comment seems unrelated to the topic of this bug report. Thanks a lot!

Thanks a lot for your suggestion.
This is the first time I'm using Phabricator.
Will do
Best regards,
