does the cloudron npm need an update? what version is it?
where i run cloudron CLI and 7.5.4 on Cloudron Builder Server. Seems to be same problem here maybe.
Some Issue with Name with new Cloudron Registry UI App
Maybe is here some problem with Cloudron build and subdomain. My Repo is with subdomain docker.kallados.com
cloudron build --set-repository Enter repository (e.g registry/username/it.kutt.cloudronapp): docker.kallados.com/kallados/short

If i use just just
cloudron build --set-repository Enter repository (e.g registry/username/it.kutt.cloudronapp): 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.

So i got it successfully and pushed into Registry on Cloudron. I had just to use Docker and not Cloudron Builder.

docker.io is the default, unless overidden with a private registry.
@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.
@msbt Nice guide!
There is something that I miss tho.
I like to run my cloudron apps local first so I can see if everything is working as intended.
This only works to a certain level for example this can't work if a database addon is used.
But everything before that step can be tested locally.
A full local test suite would be awesome, so I the developer don't have to push every test and deploy it.
For example this is how I do some local testing before I push my image.
Needed software is
jqfor json parsing,
Script explained with words:
- Get the ID and version Tag from the
CloudronManifest.jsonand use them for docker build.
- Create local folders for
/runso I can emulate cloudrons readonly behavior.
- Cleanup local folders so every test is fresh and clean
- Build the docker image with Data from
- Run the freshly build Image in readonly mode with local test folders and an interactive bash session so I can debug / test some stuff.
#!/bin/bash set -x ID=$(jq -r ".id" CloudronManifest.json) VERSION=$(jq -r ".version" CloudronManifest.json') echo "=> Create Test Data dir" mkdir -p ./cloudron_test/data ./cloudron_test/tmp ./cloudron_test/run echo "=> Cleanup Test Data" rm -rf ./cloudron_test/data/* ./cloudron_test/tmp/* ./cloudron_test/run/* echo "=> Build test image" docker build -t dr.cloudron.dev/$ID:$VERSION . echo "=> Run $VERSION tag of build image of $ID" docker run -ti --read-only \ --volume $(pwd)/cloudron_test/data:/app/data:rw \ --volume $(pwd)/cloudron_test/tmp:/tmp:rw \ --volume $(pwd)/cloudron_test/run:/run:rw \ dr.cloudron.dev/$ID:$VERSION \ bash
- Get the ID and version Tag from the

ID=$(jq -r ".id" CloudronManifest.json) VERSION=$(jq -r ".version" CloudronManifest.json)
This does one better than just stripping quotes since it will also decode other escaped characters (not that that applies in this case).
@infogulch RTFM myself nice catch, thanks for that.
