无法访问 kubernetes 集群上的本地证书

Question

I have a node application running in a container that works well when I run it locally on docker.

When I try to run it in my k8 cluster, I get the following error.

 kubectl -n some-namespace logs --follow my-container-5d7dfbf876-86kv7
> code@1.0.0 my-container /src
> node src/app.js
Error: unable to get local issuer certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1486:34)
    at TLSSocket.emit (events.js:315:20)
    at TLSSocket._finishInit (_tls_wrap.js:921:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:695:12) {
  code: 'UNABLE_TO_GET_ISSUER_CERT_LOCALLY'
}

This is strange as the only I run the container with

        command: ["npm", "run", "consumer"]

I have also tried adding to my Dockerfile

npm config set strict-ssl false

as per the recommendation here: npm install error - unable to get local issuer certificate but it doesn't seem to help.

So it should be trying to authenticate this way.

I would appreciate any pointers on this.

Here is a copy of my.yaml file for completeness.

Answer 1

It looks that the pod is not mounting the secrets in the right place. Make sure that.spec.volumeMounts.mountPath is pointing on the right path for the container image.
