Preflight Check Timeout i/o Error When Using Proxy with Terraform Enterprise

Problem

You may encounter the error below when either attempting to upgrade Terraform Enterprise (TFE), or executing replicatedctl preflight run locally within the TFE server.

✗ ERROR: Get "https://registry.replicated.com/v2/": dial tcp 162.159.138.43:443: i/o timeout
- Can access registry registry.replicated.com

✗ ERROR: Get "https://index.docker.io/v2/": dial tcp 18.233.136.226:443: i/o timeout
- Can access registry index.docker.io

Cause

• There is a known issue within the Replicated application that causes the installation script to not successfully create the setting for HTTPS communication automatically with the proxy server address provided as the value for the http-proxy flag

Note: Replicated is a third-party wrapper application that is used to deploy and manage the TFE application.

Solutions

• Upgrade Replicated to the latest version using this article
  • This bug was fixed in version Replicated version 2.54.0

• Manually set the proxy configuration for HTTPS:

  1. SSH into your TFE instance
  2. Vim or nano into /etc/default/replicated or /etc/sysconfig/replicated, depending on your Operating System
  3. Append the value for REPLICATED_OPTS with -e HTTPS_PROXY=<http-proxy-here>
  4. Execute systemctl daemon-reload
  5. Execute systemctl restart replicated
  6. Verify that replicated has finished restarting by running this command until you see the value for Replicated and Retraced as ready: watch replicatedctl system status
  7. Check that the variable was properly set by running docker exec -it -u 0 replicated env
  8. If it applied successfully, attempt the upgrade or preflight check command again

Outcome

If the proxy server is configured correctly, then you should see the previously errored checks pass successfully.

Additional Information

• This issue has been acknowledged to exist within Replication version 2.53.7. This issue may exist within previous versions, but is known to be fixed within Replicated version 2.54.0
