error on bootstrapping flux

[sanjvij]

Hi . I am having a hard time in setting up flux on my Mac using bootstrap. when I try to run bootstrap command I get a health check error as below. Am I okay to ignore this ? Apologies if this is not the right forum and feel free me to direct in that case.

The failure happens on your cluster, is it Kubernetes on Docker for Mac? Can you post here the output of these commands:

flux check
flux get sources all
flux get kustomizations

Hi. yes its happened in Kubernetes on docker for Mac. Output of commands as below

This is my third attempt as later on I get error in cloning sources and I was wondering if this was the reason. Thanks for a prompt reply

Looks like the error was transient, as the state of the resources now reflects that they could download and apply the artifact successfully.

[stefanprodan]

Flux looks OK now, my guess is that the outbound network connection was really slow and it took some time for source-controller to clone the repo.

[sanjvij]

Okay thanks . So reason I wonder this was the issue was due to failure in creating sources. I will carry on and see if the sources get created successfully this time. thanks again.

Hi Stephan,

So reason I was trying to setup flux again was down to this error on creating sources. I am still new to this so feel free to correct me. When I create the source, I am getting the below error. the error is obvious as in it's missing authentication but I am not sure why the flux-system (default source I am guessing) is able to talk to git-hub but not the custom source named staging that I created. I have also pasted the content of the staging file.

I see something similar, all the resources are healthy but there is one timeout which doesn't give enough details as to what went wrong.

Any leads would be appreciated.

@sanjvij You have to specify a secret containing the git credentials in spec.SecretRef in GitRepository CRD if the repository is private/ requires authentication. The reason that that flux-system can talk to GitHub is because this was automatically done for you during the bootstrap process.
See docs

[sanjvij]

Thanks. for time being I simply injected value from env variables. But Agree with your approach. Also the original bootstrapping error didn't came when I ran the bootstrap command again so am happy to close this as not an issue

@jdeokar95 I read somewhere that the solution to your problem is proxy related, running:

unset http_proxy
unset https_proxy

worked for me. Can't give you more info than that, but it fixed the problem for me on an Ubuntu VM and on my Mac :)
