500 ERROR code when connecting keycloack to kapua (connection time out)

[amelroua]

I want to deploy SSO with keycloak. I tried to use the keyloak image and kapua image used in the

sso-docker-deploy.sh script
But I get everytime the same error of connection timeout between kapua console and keyloak

HTTP Error Code: 500
Requested Resource: /openid/callback
Error Message: javax.servlet.ServletException: javax.servlet.ServletException: Failed to get tokens: Error:
Exception Message: Connection timed out (Connection timed out)

Then I tried to use my own image with the set up of JAVA_OPTS and I get the same error everytime. I think that the problem is a connection issue between kapua and keycloak. But both kapua console and keycloak can ping each other.
I used KAPUA_URL: http://localhost:8080
for keycloack I tried with the public IP@: 172.18.xx and also with my host IP@ 192.168.xx but the same error is remaining.
But when I used the localhost for keyloak I get connection refused instead of connection time out.

I found that the problem is that kapua console cannot connect to the token endpoint of keyloak. when i tried to execute a curl command from kapua console container to get an access token:
curl -d 'client_id=console' -d 'username=admin' -d 'password=admin' -d 'grant_type=password' 'http://172.18.xx:port/auth/realms/kapua/protocol/openid-connect/token' | python -m json.tool
I have the same issue
But when I execute the curl command from my local host I can get an access token.

Any idea please how to solve this issue?

Can you reach Keycloak on localhost:9090 anche the Kapua Console at localhost:8080?
Anyway, please use KAPUA_CONSOLE_URL and not KAPUA_URL as you mentioned, since that should be the correct env variable. If you correctly populate both that one and KEYCLOAK_URL as mentioned at

kapua/assembly/console/entrypoint/run-console

Lines 17 to 20 in 64dde70

	if [ -n "$KEYCLOAK_URL" ] && [ -n "$KAPUA_CONSOLE_URL" ]; then
	echo "Activating OpenID Connect Keycloak integration..."
	echo " Keycloak: $KEYCLOAK_URL"
	echo " Kapua: $KAPUA_CONSOLE_URL"

you should see a log entry that tells you the current configuration
