Our team is using the console-plugin-template as a base for the project:https://github.com/artemiscloud/activemq-artemis-self-provisioning-plugin

We are using the M1 chip MacBooks and when we run yarn run start-console and access http://locahost:9000, the following error comes up.

Steps to reproduce

  1. clone https://github.com/artemiscloud/activemq-artemis-self-provisioning-plugin.git
  2. cd activemq-artemis-self-provisioning-plugin
  3. run yarn run build (should have yarn installed)
  4. run yarn run start in a separate terminal
  5. run yarn run start-console in another terminal

Expected

The UI should be accessible at http://localhost:9000

I would be great if you could assist us in finding the exact issue. Thanks in advance.

Hey @AjayJagan,

can you check if your crc configuration in /etc/hosts match the output of crc ip?

AjayJagan commented

Hi @jerolimov , thanks for your reply. So the output of

crc ip is -> 127.0.0.1

my /etc/hosts/ file has the following entry ->

127.0.0.1 localhost api.crc.testing canary-openshift-ingress-canary.apps-crc.testing console-openshift-console.apps-crc.testing default-route-openshift-image-registry.apps-crc.testing downloads-openshift-console.apps-crc.testing oauth-openshift.apps-crc.testing

I'm also just a CRC user and not involved there in details.

On my Linux machine, it uses a 192.168.x.x address. Returned by crc ip and then I have another line in my /etc/hosts. But when checking the CRC issue tracker (https://github.com/crc-org/crc/issues?q=crc+ip+localhost) it looks like localhost is fine on Windows and Mac.

But this console output should be the problem:

2022/11/21 05:28:45 http: proxy error: dial tcp: lookup api.crc.testing on 192.168.127.1:53: no such host

start-console.sh is using oc whoami --show-server to check which IP address your server uses. Is the CRC server the last server you logged in with oc or kubectl?

Please check

oc whoami
oc whoami --show-server

I use this login command before starting the console:

oc login -u kubeadmin -p $(cat ~/.crc/machines/crc/kubeadmin-password) --server https://api.crc.testing:6443

But I'm unsure if the CRC kubeadmin password is saved on a Mac at the same spot. You can try to replace it with the password that CRC prints at the end of crc start.

Hey @jerolimov ! Thanks a lot for the reply!! so when I ran
oc whoami -> kubeadmin
oc whoami --show-server -> https://api.crc.testing:6443

Also what I do to login is use the webconsole -> there is is copy login command on the top right drop down.. which gives the token to login - maybe that is the issue?

When checking the error again:

2022/11/21 05:28:45 http: proxy error: dial tcp: lookup api.crc.testing on 192.168.127.1:53: no such host

It says 192.168.127.1:53: no such host, port 53 is DNS. So the lookup for this doesn't work, and the reason is that this is not a lookup on your machine directly. It tries to solve within the console container.

At the end of start-console.sh you can see that it uses podman or docker, depending if it is installed or not. And in this console container image, the hostname "api.crc.testing" is unknown.

As a workaround or test you can set the BRIDGE_K8S_MODE_OFF_CLUSTER_ENDPOINT variable in start-console.sh to an IP address (in the format https://127.0.0.1:6443 or https://192.168.x.y:6443) of your mac. The console container should have a way to connect to your CRC.

Hi thanks for the suggestions again :) but the issue is - I tried replacing BRIDGE_K8S_MODE_OFF_CLUSTER_ENDPOINT with two of the options and got the following results

  1. https://127.0.0.1:6443 - 2022/12/19 08:08:38 http: proxy error: dial tcp 127.0.0.1:6443: connect: connection refused
