502 Bad Gateway for all components (Control Center, Kafka Connect) after applying terraform script
JustinMoser opened this issue · 2 comments
Hi,
We are a recent Confluent Cloud customer and I have successfully deployed the Confluent Platform tools from this repo onto AWS EC2 (Ubuntu) using the steps in your Readme, resulting in this output after applying the Terraform script:
Bastion_Server = ssh ec2-user@REDACTED -i cert.pem
Control_Center = http://control-center-ccloud-tools-REDACTED.eu-west-2.elb.amazonaws.com
KSQL_Server = http://ksql-server-ccloud-tools-REDACTED.eu-west-2.elb.amazonaws.com
Kafka_Connect = http://kafka-connect-ccloud-tools-REDACTED.eu-west-2.elb.amazonaws.com
REST_Proxy = http://rest-proxy-ccloud-tools-REDACTED.eu-west-2.elb.amazonaws.com
However, when I navigate to any of those urls I receive a 502 Bad Gateway response.
Is this the desired output? Im not sure how to go about accessing any of these tools.
I tried (for instance):
curl -sX GET "http://ksql-server-ccloud-tools-REDACTED.eu-west-2.elb.amazonaws.com/info"
and I still receive a 502 Error.
Any ideas if I am doing something wrong? Additionally, the topics that should be created by Control Center when it starts, as listed at this link:
https://docs.confluent.io/current/cloud/connect/c3-cloud-config.html
Are not listed when running ccloud kafka topic list
It seems as though none of the Cloud Tools have initialised properly...

FYI anyone facing this issue:
This was caused by using the Ubuntu Server AMI instead of the Amazon Linux 2 AMI.
