How to build (custom) apps using the docker-registry
-
Since I was documenting what I was doing to debug errors, here's a short how-to for people who want to use the docker-registry app with authentication to build their own apps. Before submitting I realized that @girish already made a post here, but that was without the registry so I'm posting it either way
Prerequisites:
A machine that has both, docker and the cloudron cli installed and of course one or two Cloudrons for the apps to build and/or install
Docker: https://docs.docker.com/engine/install/ubuntu/
Cloudron CLI: https://docs.cloudron.io/custom-apps/cli/How to build apps and push to your Docker-Registry
install the docker-registry app on a cloudron (if possible don't use a production server), e.g. docker.example.com (you might want to create a dedicated user to work with it). Add the URL and docker credentials to your target cloudron in Settings / Private Docker Registry
Optional: use the Cloudron Build Service
install the Build Service app, e.g. https://build.example.com, open the terminal or file manager of the app and enter your docker credentials in
/app/data/docker.json. After those changes reboot the build service app to make sure the correct registry is in there. You can directly login to your build service (no trailing slash in the url! see https://docs.cloudron.io/apps/build-service/ for more information) via
$cloudron build --set-build-service(enter https://build.example.com)clone any repo you want to build
$git clone https://git.cloudron.io/cloudron/lamp-appcwd into the cloned git directory
$cd lamp-app/With local build
login to the docker-registry with your credentials (as non root user you might need to use sudo when issuing docker commands)
$docker login docker.example.combuild the thing (use custom lamp-app:tags if you want specific tag names)
$docker build -t docker.example.com/lamp-app .push to the registry - this does not work without logging in first
$docker push docker.example.com/lamp-appinstall on your target cloudron after logging in via
cloudron login
$cloudron install --image docker.example.com/lamp-appWith the Build Service
If you're using the build service, you can just run
$cloudron buildand enter your docker-repo (e.g.docker.example.com/lamp-app)
and after logging in to your cloudron
$cloudron install --image docker.example.com/lamp-appIf you updated an app, you can use
cloudron updateto push a new version for an existing app.Cheers, M

Thanks for it. I think, i do something wrong here and get every time error
Docker.json has been set. I can find on the build.website also the new Image. But this image is later not pushed to my own private repository and want to push it to docker.ioroot@v220201270340135516:~/shortener# cloudron build Using build service https://build.kallados.com Building docker.kallados.com:20210213-171725-92029c79a Uploading source tarball...

@kallados said in How to build (custom) apps using the docker-registry:
Building docker.kallados.com:20210213-171725-92029c79a
Unrelated to the docker registry: This doesn't look right, you're missing the app-name. You should enter
docker.kallados.com/my-appafter triggering cloudron build -
Ah, good spot! That would indeed be a problem if you don't have the org name and repo name correct when building. You can "reset" the repo name with
cloudron build --set-repository. Note that if you are using public docker registry, it should be likeusername/my-app-repo -
@msbt Im not sure, what you mean. Btw. where you mean. I changed some steps now, bit testing... and i have on the Docker "own version" of Kutt Shortener... Bit this image have 727 MB.. Pretty big. But this is maybe normal. I see noe the App in Cloudron Dashboard, but is not running. I get this again from scratch.

Successfully tagged kallados/shortener:20210214-211904-2725dd144 The push refers to repository [docker.io/kallados/shortener]But docker.io has been nowhere stored from me. docker.json on Builder is correct.
*** I have tried to enter a port. Interesting why IPv6 pops out... but at least I get response from the server.
Successfully built 40310b79e0c2 Successfully tagged gd.life:8000/kallados/short:20210214-221223-9816a45d7 The push refers to repository [gd.life:8000/kallados/short] Get https://gd.life:8000/v2/: dial tcp [xxx:3549::3]:8000: connect: no route to host Failed to build app. See log output above.So i got it successfully and pushed into Registry on Cloudron. I had just to use Docker and not Cloudron Builder.

@kallados I think the issue you hit is that 6.1.2 has a bug where pushing from a custom docker client fails (in this case, the docker client is the build service). https://forum.cloudron.io/topic/4383/cannot-install-apps-from-docker-registry-because-authentication-fails/8 has the fix.
Nice to get the full circle with the registry app
