<![CDATA[Building custom app - authentication problem]]>I am building my first custom app in Docker in Python and I want to host it on Cloudron.
Currently, the repository is set up on docker.com. I have set up the repository in the cloudron settings using an access token. I have a CloudronManifest.json, a Dockerfile and the requirements file (since it's python), but I am stuck when running

cloudron build

as I consistently run into this error message:

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7fc9470e4750>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/asgiref/

The same comes with any other package that happens to be the first in the requirements file.

I am the owner of the Docker repository.

Does anyone know what I can do about it?

There was indeed a bug that the dashboard code throws an error when an app does not use any addons. https://git.cloudron.io/cloudron/box/-/commit/e02f3d70649c75c64e4126f1deea45b3456277a0 is the fix.

Can you please reach out at support@cloudron.io, interested to see what's going on.

I corrected some other errors and finally got the message "app is installed" at some point without any error message. However, once that is the case, I cannot access the dashboard anymore (it stays grey, see above) until I uninstall the app.

Maybe that is a support case after all where you ssh into my instance?

Did you take this into account?

I could now build the app using cloudron build but I am getting this when I am trying to install it:
App installation error: Installation failed: Unable to pull image PATH:tag. message: (HTTP code 404) unexpected - pull access denied for PATH, repository does not exist or may require 'docker login': denied: requested access to the resource is denied statusCode: 404

But the path is right, I used --set-repository to check and it's the same I use for docker pull and docker push.

Is it possible that for whatever reason Cloudron cannot authenticate with Docker in my case?

EDIT: It works when making the repository public.

I also suspect that it is an IP restriction because I am currently in Malaysia. So, I contacted Docker support about it. The only other solution I could think of then would be to change the docker repo provider to Google or something.

error parsing HTTP 403 response body: invalid character '<' looking for beginning of value: "<html>\r\n<head><title>403 Forbidden</title></head>\r\n<body>\r\n<center><h1>403 Forbidden</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n"
Failed to push image (are you logged in? if not, use "docker login")

But I ran docker login before this step. I completely deleted all Cloudron CLI configuration and re-installed it without any effect.

Instead, I just get a faulty installation in the first place.

and uninstalling the app via CLI immediately solved it.

FWIW when I am building a custom app and I make changes to the Dockerfile, it is my standard process to uninstall the last app version before seeking to build and deploy the next version.
Technically this might be unnecessary, but for my little brain, I find it easier to know that I am starting 'clean'.
I usually uninstall via the app's settings screen, but I guess from CLI is same and might be easier if you're working on command line anyway.

I also use a little script cld.sh (call it whatever you want, I save keystrokes where possible) :

#/bin/bash
docker build --no-cache -t $1 .
docker push $1
cloudron install --image $1

and I run this it this : ./cld.sh <repository_url>/<app_name>:<tag>
I hack my way through multiple trial-and-error builds, and this saves a lot of time, keystrokes and typos.

Maybe you have your own workflow efficiencies 😄

EDIT: --tag did that

However it should certainly not bring down the whole dashboard.

"cloudron stop --app NAME"
using Cloudron CLI

but it says
"Failed to stop app: 409 message: Not allowed in error state"

But this worked:
"cloudron uninstall --app NAME"

So, I got access to the dashboard again.

The 3 stopped apps are okay, that's intended.

Do you see any errors in the browser logs or at /home/yellowtent/platformdata/logs/box.log ?

I got to run "cloudron install --image" after building the docker successfully. But I ran into another particular problem.

Firstly, when running the command, I got this error message:
App installation error: Installation failed: Unable to pull image PATH. message: (HTTP code 404) unexpected - pull access denied for PATH, repository does not exist or may require 'docker login': denied: requested access to the resource is denied statusCode: 404

So, I made sure I was logged in.

Secondly, I tried to run the command again and got this:
Failed to install app: 409 message: primary location 'PATH' is in use
(I could probably just specify a new path, it's not critical, but to keep it clean it would be great to know how to delete the failed attempt)

However, the Cloudron dashboard doesnt load anymore. It stays grey. If I try to log in in another browser, I get to the login mask, after putting in my details, I just see a grey screen. Fortunately, apps seem to work still, I can access them separately.

Independently of the actual docker error, that is an odd behaviour. I'll try to go through the tutorial for how to save cloudron next unless I see something specific in this thread.

Not sure where you are pushing to, did you set the right image name ? You can try cloudron build --set-repository. Here, you should enter something like ekevu123/appname (where ekevu123 is your docker hub username and appname is the repository).

But I found the issue - apparently, you can not do that when being on VPN.

Now I get this error message in the end:
error parsing HTTP 403 response body: invalid character '<' looking for beginning of value: "<html>\r\n<head><title>403 Forbidden</title></head>\r\n<body>\r\n<center><h1>403 Forbidden</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n"
Failed to push image (are you logged in? if not, use "docker login")

However, I am logged in (I ran "docker login" right before executing "cloudron build").

It seems this is a general Docker building issue. So, much depends on your platform / OS as well. Is this a Mac or Windows or Linux ?

Usually, the best way to debug Docker build issues is something like:

  • First run, docker run -ti cloudron/base:4.0.0 /bin/bash . This will give you a bash prompt.
  • Now, execute the commands in your Dockerfile one by one in the prompt and see where it breaks.

But alright, I appreciate the help I am getting here!

Regarding the questions above:

  1. I have removed the link to the docker image from the Cloudron manifest and tried to run "cloudron build" again, which gets me stuck here again:
    Step 4/6 : RUN pip install --no-cache-dir -r requirements.txt
    ---> Running in e834d414ac34

  2. Now I am trying to build the docker image without Cloudron, see above, and I am getting the same issue.

The requirements file I am getting stuck with looks like this:
asgiref==3.6.0
beautifulsoup4==4.12.2
certifi==2022.12.7
(and more following)

It doesn't help to simply delete a few requirements, it will always hang with the first one in the file.

One shouldn't specify a static docker image in the manifest.

"dockerImage": "link-to-image:tag",

For my education, is this line needed in the manifest file? because we are building the Dockerfile to produce an image.
I've never used this line when building a custom package
