Export Docker Mongo Data

1. You can run Wekan on Docker locally like this on http://localhost:8080/ (or other port it you change 8080 in script):

docker run -d --restart=always --name wekan-db mongo:3.2.11

docker run -d --restart=always --name wekan --link "wekan-db:db" -e "MONGO_URL=mongodb://db" -e "ROOT_URL=http://localhost:8080" -p 8080:80 mquandalle/wekan:latest

Mongo 3.2.11 used because of bug in 3.4.1:

https://github.com/wefork/wekan/issues/58

2. List docker containers, your ID:s will be different:

docker ps

Result:

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES
1234wekanid        mquandalle/wekan    "/bin/sh -c 'bash $ME"   About an hour ago   Up 46 minutes       0.0.0.0:8080->80/tcp   wekan
4321mongoid        mongo               "/entrypoint.sh mongo"   About an hour ago   Up 46 minutes       27017/tcp              wekan-db

3. Enter inside mongo container:

docker exec -it wekan-db bash

4. OPTIONAL: If you want to browse data inside container, you can use CLI commands like listed at

https://docs.mongodb.com/manual/reference/mongo-shell/

like this:

> mongo             <==== START MONGO CLI

5. Go to /data directory:

cd /data

6. Backup database to files inside container to directory /data/dump, only Wekan database with name "admin" is included, not local:

mongodump

7. Exit from inside of container:

exit

8. Copy backup directory /data/dump from inside of container to current directory:

docker cp wekan-db:/data/dump .

9a) Restore backup later:

docker cp dump wekan-db:/data/
docker exec -it wekan-db bash
cd /data
mongorestore --drop
exit

9b) Or restore to another mongo database, in different port:

mongorestore --port 11235

10. If you would like to browse mongo database that is outside of docker in GUI, you could try some admin interface:

https://docs.mongodb.com/ecosystem/tools/administration-interfaces/

11. If you sometime after backups want to remove wekan containers to reinstall them, do:

docker stop wekan wekan-db
docker rm wekan wekan-db

Then you can reinstall from step 1.

12. If latest version of Wekan Docker image is broken, here's how to run older version:
