Trouble upgrading to 0.4.
We tried upgrading from 0.3 to 0.4 with the following steps
- creating a dump of the Postgresql database mailmandb
- setting the images mailman-web and mailman-core in docker-compose.yaml from Version 0.3 auf Version 0.4: image: maxking/mailman-core:0.4 image: maxking/mailman-web:0.4
- then updating postgresql: image: postgres:10.1-alpine
- deleting the directory /opt/mailman/database
- calling docker-compose up -d the new containers were received and started
- now the database dump was imported again
Looking at the log of the mailman-core-container, at the end the following error is shown: sqlalchemy.exc.NoSuchModuleError: Can't load plugin: sqlalchemy.dialects:postgres
What else is there to do? Any help would be appreciated, thanks!
Can you update postgres to postgresql in the DATABASE_URL?
With newer versions of sqlalchemy, I think 'postgres' is no longer valid.
Actually, that might not be the case. THe newer release will have that issue and it is still not out.
Can you send output of docker images | grep mailman?
Sorry for the late reply, we didn't have time to try the update again. Here's the output:
REPOSITORY TAG IMAGE ID CREATED SIZE maxking/mailman-web 0.4 3f0bc6a75e1e 8 months ago 248MB maxking/mailman-core 0.4 e435fcfc7d03 8 months ago 204MB maxking/mailman-web 0.3 9ba9d3d7084d 2 years ago 487MB maxking/mailman-core 0.3 26c920c0094b 2 years ago 178MB postgres 9.6-alpine aa87de9a5e0f 5 years ago 39.2MB postgres 10.1-alpine e6c5e6a76255 5 years ago 38.2MB
Updating the scheme scheme in DATABASE_URL helped us.
Plus the behaviour seen in
- #614
disappeared.
