* Updating the charm to a new version * Updating the charm to a new version
We are using official image. Latest tags usually. You can

We are using official image. Latest tags usually.
#+begin_src sh
docker search rocket.chat
#+end_src
** Test new version
Rocket.chat has a powerfull and working database update mecanism that
will take care of migrating database on startup.
So we usually pull and test images like this :
*** Get latest available versions
You can double-check available candidate for official images like this:
#+begin_src sh #+begin_src sh
docker pull rocket.chat:X.Y.Z
docker-tags-fetch rocketchat/rocket.chat -l 15 -f "^[0-9]+\.[0-9]+\.[0-9]+$" | sort -rV
#+end_src #+end_src
This worked on 3.6.3, but changed before 3.8.0 to:
Check/Choose the version you want to test.
#+begin_src sh
docker pull rocketchat/rocket.chat:X.Y.Z
*** Modify your own =compose.yml=
By adding these 2 lines in your rocket chat service:
#+begin_src yaml
docker-compose:
image: rocketchat/rocket.chat:X.Y.Z
#+end_src #+end_src
from: https://hub.docker.com/r/rocketchat/rocket.chat
Replace X.Y.Z by the target version you want to test.
Launch =compose up=.

service to be available: rocketchat is expected to take some time to
migrate.
Get the available tags:
** Change the current charm to include new version
To prepare the commit for next version, you can run the following

#+begin_src sh #+begin_src sh
docker-tags-fetch rocket.chat -l 15 -f "^[0-9]+\.[0-9]+\.[0-9]+" | sort -V
BASENAME=rocketchat/rocket.chat
VERSION=$(docker-tags-fetch "$BASENAME" -l 15 -f "^[0-9]+\.[0-9]+\.[0-9]+$" | sort -rV | head -n 1)
echo Last version of rocket chat: $VERSION
docker pull rocketchat/rocket.chat:"$VERSION" &&
docker tag rocketchat/rocket.chat:"$VERSION" docker.0k.io/rocketchat:"$VERSION" &&
docker push docker.0k.io/rocketchat:"$VERSION" &&
sed -ri "s%^(docker-image: docker.0k.io/rocketchat:).*%\1$VERSION%" metadata.yml &&
sed -ri "s%^(#docker-image: rocketchat/rocket.chat:).*%\1$VERSION%" metadata.yml
#+end_src #+end_src
