As of release 2.54.0, the gremlin/gremlin container image is no longer based on Alpine Linux.
In order to troubleshoot network issues that would previously have involved tools included on the agent image, it is recommended to utilize kubectl debug in order to create an interactive debugging session on the gremlin pod with the required troubleshooting tools (such as curl, openssl, etc.)
It is possible to run individual commands, as in this example where the pod uses 'curl' to contact the gremlin API:
kubectl debug gremlin-pod -n gremlin -it --image=curlimages/curl --attach -- curl -vvv https://api.gremlin.com/v1/health
Alternatively, you can perform troubleshooting interactively from a pod by adding it directly to your node (the netshoot image is a common choice for troubleshooting network issues, as it includes a variety of common useful tools):
kubectl debug -it --profile=sysadmin node/node-name --image=nicolaka/netshoot -- sh
The inclusion of sysadmin profile may itself allow for installation of packages onto your images using the corresponding package manager.
