how to migrate these dockers to other host ?

[yungang]

I had installed taigadocker on one host, but now I need migrate them to a new host, what should I do ?

I meet the same problem.

there are two methods, one, do a new install & migrate, or 2, commit container, save image, then load image on new hosts.
method 1, new install and migrate(i think this is the simplest way):
1，export db 'taiga' from postgresql, user is taiga and password is password just as in taiga.yml
#pg_dumpall -Utaiga > taiga.sql
2, backup directores media and static on taiga-back container
3, reinstall taiga dockers
4, restore media and static directories and import taiga.sql
done

method 2, save images and re-load images:
1, docker commit and save docket taiga-front and taiga-back
2, docker save docker-front and docker-back
3, move images to new hosts
4, docker load images and create containers

docker run -it --name postgres postgres /bin/bash

docker run --name taiga-back  --expose 8000 --link postgres:postgres taigadocker_taigaback:backup /usr/local/taiga/start

docker run -p 80:80 --expose 80 --expose 554  --name taiga-front --link taiga-back:taigaback --volumes-from taiga-back taigadocker_taigafront:backup /usr/local/taiga/start

-- by the way ,now taiga 3.0 has been released, so, i think you need upgrade, see Dockerfile of taiga-back and taiga-front, you will see how to do
BUT, do remember run
manage.py loaddata initial_project_templates --traceback
on taiga-back container after you upgrade, otherwise you will failed when you create new projects.
