5.3 The API Endpoint

The snippet from this slide suggests us to ssh the minikube VM then to curl the API.

When I tried this I ran into the issue that minikube VM doesn't come with curl. 

After looking at some docs, I took another approach (and write this here in case other student wonder how to curl the API)

From my host machine, I ran 

kubectl proxy --port=8080 --api-prefix=/

To proxy the api endpoints on my localhost


I'm now able to curl the api with 

curl http://localhost:8080/apis | jq

curl http://localhost:8080/api

curl http://localhost:8080/api/va


Hope this might save some time to other students with the same issue.

    Unfortunately it looks like you are correct.

    The base OS used in minikube changed in v0.15.0 and curl is not available any more.

    I created a bug upstream to get it back: https://github.com/kubernetes/minikube/issues/1059

    In the meantime, I will update the course .

    thanks for reporting this and apologies for the lost time,


  • Thank you for this!  Out of curiousity, which doc did you find that provided this information?

  • This actually does not seem to work completely for me.  I ran the proxy command and got

    Starting to serve on

    which seems to be expected.  Then I opened up another shell and attempted to curl


    I got the same result when trying to sudo.

  • Figured it out.  I have to hit the endpoints listed above directly.  I couldn't just hit local host on 8080 with specifyin a uri.

    Kubernetes developers are putting curl again in the newest version of minikube, so this should not affect folks once there is a new release of minikube.

  • Great news!

    @ryankbales , re your question about the doc... to be honest I don't remember (there are so many docs out there!) I came across this after some googling to try to find out how to make this works ;-)

    This is how you can connect to the api with the minikube 0.22.3


    $ APISERVER=$(kubectl config view | grep server | cut -f 2- -d ":" | tr -d " ") $ TOKEN=$(kubectl describe secret $(kubectl get secrets | grep default | cut -f1 -d ' ') | grep -E '^token' | cut -f2 -d':' | tr -d '\t') $ curl $APISERVER/api --header "Authorization: Bearer $TOKEN" --insecure { "kind": "APIVersions", "versions": [ "v1" ], "serverAddressByClientCIDRs": [ { "clientCIDR": "", "serverAddress": "" } ] }

    Or you can simply run a proxy `kubectl proxy` and then `curl localhost:8001/api`

    @sebgoa, the course has not been updated yet, not in the PDF, nor in the course itself.

    Indeed if you run a "kubectl proxy" that will start to serve on your machine on and you can then curl as you mentioned above.
