Log aggregation of replicas #5714

Open yujunz opened 3 years ago

yujunz commented 3 years ago

Summary

Aggregate logs of all pods of parent resources like ReplicaSet, Deployment, DaemonSet, Statefulset and etc.

Motivation

Pod logs in Argo CD UI are very helpful for troubleshooting but not good enough for multiple replicas.

Proposal

Support logs under the parent resource view, similar to what is available to Pod, but aggregating all logs from child pods.

This is coming in v2.0. See a preview of the feature here:

The colored dots indicates output from a different replica.

There is a hard limit of total replicas it can stream from. I believe this might be 10.

Superb.

Is it already in the master branch? @jessesuen

It seems available for Deployment from the latest build.

Can we add it to Service as well? I often use the Network view for complex application but Deployment is not visible in it.
