Local Troubleshooting

Troubleshooting Opta Local


If things don’t seem to be working as expected, here are some places to start debugging Opta Local


Opta Local runs two containers on the local machine. Confirm both are running; like so

# Command
 docker ps

 # Output
CONTAINER ID   IMAGE                  COMMAND                  CREATED      STATUS        PORTS                                                                    NAMES
71d2f8a13961   kindest/node:v1.21.1   "/usr/local/bin/entr…"   2 days ago   Up 10 hours>80/tcp,>443/tcp,>6443/tcp   opta-local-cluster-control-plane
ac9b78c91776   registry:2             "/entrypoint.sh /etc…"   2 days ago   Up 10 hours>5000/tcp                                                 opta-local-registry

If these containers are not running, then debug the docker containers so Opta Local can start correctly.

Kind Kubernetes Cluster

  1. Confirm that the kubectl context is correctly set.
# Command
kubectl config get-contexts  
# Output
*         kind-opta-local-cluster                                        kind-opta-local-cluster                                        kind-opta-local-cluster     

Note the “*” in front of the kind-opta-local-cluster. In case the current context is not set to the kind cluster, you can set it like so:

# Command
kubectl config use-context kind-opta-local-cluster
# Output
Switched to context "kind-opta-local-cluster".
  1. Check that the Kind Kubernetes Cluster is functioning
# Command
kubectl cluster-info
# Output
Kubernetes master is running at
CoreDNS is running at

# Command
kubectl cluster-info
  # Output
Kubernetes master is running at
CoreDNS is running at

To further debug and diagnose cluster problems, use kubectl cluster-info dump and kubectl get node

# Command
kubectl get node
# Output
  NAME                               STATUS   ROLES                  AGE   VERSION
  opta-local-cluster-control-plane   Ready    control-plane,master   14m   v1.21.1
  1. You can interact with the local Kubernetes cluster with the kubectl cli tool. Browse through additional kubectl commands here

Container Registry

Opta Local creates a local Docker container registry at http://localhost:5000. This is used during Opta Deploy to host your images. Confirm it is functioning:

  1. Curl the address http://localhost:5000/v2/
  # Command
  curl -v http://localhost:5000/v2/ 

  # Output
  *   Trying
  * Connected to localhost ( port 5000 (#0)
  > GET /v2/ HTTP/1.1
  > Host: localhost:5000
  > User-Agent: curl/7.68.0
  > Accept: */*
  * Mark bundle as not supporting multiuse
  < HTTP/1.1 200 OK
  < Content-Length: 2
  < Content-Type: application/json; charset=utf-8
  < Docker-Distribution-Api-Version: registry/2.0
  < X-Content-Type-Options: nosniff
  < Date: Mon, 27 Sep 2021 02:05:38 GMT
  * Connection #0 to host localhost left intact

Note the 200 OK Http response and the {} braces in the output.

  1. Confirm that images can be tagged and pushed into the docker registry. Example:
  # Command
  docker pull alpine

  Using default tag: latest
  latest: Pulling from library/alpine
  a0d0a0d46f8b: Pull complete 
  Digest: sha256:e1c082e3d3c45cccac829840a25941e679c25d438cc8412c2fa221cf1a824e6a
  Status: Downloaded newer image for alpine:latest
  # Command
  docker tag alpine:latest localhost:5000/alpine:latest
  docker push localhost:5000/alpine:latest 
  # Output
  The push refers to repository [localhost:5000/alpine]
  e2eb06d8af82: Pushed 
  latest: digest: sha256:69704ef328d05a9f806b6b8502915e6a0a4faa4d72018dc42343f511490daf8a size: 528

Clean up and start over

If you are stuck and are unable to troubleshoot the issue that you are facing, you can start over.

Follow these instructions to clean up the local environment and run opta apply again.
