This script allows you to aggregate (tail/follow) logs from multiple pods into one stream. This is the same as running "kubectl logs -f " but for multiple pods.
First find the names of all your pods:
$ kubectl get pods
This will return a list looking something like this:
NAME READY STATUS RESTARTS AGE
app1-v1-aba8y 1/1 Running 0 1d
app1-v1-gc4st 1/1 Running 0 1d
app1-v1-m8acl 1/1 Running 0 6d
app1-v1-s20d0 1/1 Running 0 1d
app2-v31-9pbpn 1/1 Running 0 1d
app2-v31-q74wg 1/1 Running 0 1d
my-demo-v5-0fa8o 1/1 Running 0 3h
my-demo-v5-yhren 1/1 Running 0 2hTo tail the logs of the two "app2" pods in one go simply do:
$ kubetail app2
If the pods are using multiple containers specify the container like this:
$ kubetail app2 -c container1
Supply -h for help and addtional options:
$ kubetail -h
When you press "ctrl+c" to end the log session you may end up with errors like this:
error: write /dev/stdout: broken pipeI'm not quite sure why this happens, pull requests are welcome :)
