Unable to build simple app image - following steps from blog

[jerrinsg]

Hello,

What steps did you take:

I was following along the steps mentioned in the "Deploying Kubernetes Applications with ytt, kbld, and kapp" blog.

What happened:

Under the "Building container images locally" section, the command to build the simple app image is listed as

$ kapp deploy -a simple-app -c -f <(ytt -f config-step-3-build-local/ -v hello_msg=friend | kbld -f-)

But I am seeing the following build error while running this command:

1:36:59PM: ongoing: reconcile deployment/simple-app (apps/v1) namespace: default
1:36:59PM:  ^ Waiting for 1 unavailable replicas

What did you expect:

Successful build of the app image as mentioned in the blog.

Hi @jerrinsg I followed the steps from the blog and didn't face any issue. Can you make sure that you are logged in using your docker account?

[jerrinsg]

Thanks for the response @praveenrewar. Hmm I tried again after doing docker login and still see the same.

@jerrinsg Do you see this image when you do docker images? Are you able to inspect it docker image inspect kbld:docker-io-dkalinin-k8s-simple-app-sha256-9bb10ebf4d8d467ed9a625cdf86c1bd6be6a0ab308aaf80571aca36ca4c7c5fc? I have faced a similar kind of issue once, and for me restarting my system seemed to have work. I wasn't able to debug what the issue was, but maybe you could give it a shot.

[jerrinsg]

Yes I see the image in docker images and can inspect it too:

Restarting the system didn't help too :(
