Deployment failed to create pod

I want to deploy the ingress controller, but I don't know where there is a problem with my configuration file

Who can help me? This problem has been bothering me for a long time. Thank you very much

[jasonwilliams14]

@Nihilism0 are you able to provide us with a kubectl describe on the NGINX Ingress controller deployment?
Can you also grab the events as well kubectl get events

We can start to look for events and messages to point to the issue.
Thanks

@Nihilism0 can you describe to me the environment you are installing into?
How are you deploying NGINX Ingress?
Looks like you are using version 2.2-alpine.
Are you using the correct versions of the deployment for that version?

[shaun-nx]

Hi @Nihilism0 from the output of your deployment it shows that you have 1 desired pod, and 1 unavailable pod

Replicas:               1 desired | 0 updated | 0 total | 0 available | 1 unavailable

Can you run kubectl describe on the replicaset of you deployment? This should provide us with event details from the replica set, and should tell us why it was not able to startup.
