Bash script to tail Kubernetes logs from multiple pods at the same time
Clone or download


Bash script that enables 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.


Just download the kubetail file (or any of the releases) and you're good to go.


You can also install kubetail using brew:

$ brew tap johanhaleby/kubetail && brew install kubetail

Use brew install --HEAD kubetail to install the latest (unreleased) version.


The easiest option is to install kubetail from homebrew to dynamically display the pods names on $ kubetail <tab>. Alternatively install any of the completion scripts (bash/zsh/fish) manually. For example:

  • On Ubuntu, copy the kubetail.bash script to /etc/bash_completion.d/.
  • On Mac with zsh copy the kubetail.zsh script to /usr/local/share/zsh/site-functions/_kubetail.

Don't forget to restart your terminal afterwards.


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          2h

To tail the logs of the two "app2" pods in one go simply do:

$ kubetail app2

To tail only a specific container from multiple pods specify the container like this:

$ kubetail app2 -c container1

You can repeat -c to tail multiple specific containers:

$ kubetail app2 -c container1 -c container2

To tail multiple applications at the same time seperate them by comma:

$ kubetail app1,app2

For advanced matching you can use regular expressions:

$ kubetail "^app1|.*my-demo.*" --regex

Supply -h for help and additional options:

$ kubetail -h


By using the -k argument you can specify how kubetail makes use of colors (only applicable when tailing multiple pods).

Value Description
pod Only the pod name is colorized but the logged text is using the terminal default color
line The entire line is colorized (default)
false Don't colorize the output at all


$ kubetail app2 -k false

Filtering / Highlighting etc

kubetail itself doesn't have filtering or highlighting capabilities built-in. If you're on MacOSX I recommend using iTerm2 which allows for continuous highlighting of search terms, good scrolling capabilities and multitab arrangements. Another useful feature of iTerm2 is the "timeline" (cmd + shift + e) which lets you display a timeline in your own local timezone next to the logs (that are typically in UTC).

If you're not using iTerm2 or think that kubetail is lacking in features there's a fork of kubetail made by Alan Stebbens that allows for richer configuration and uses multitail and bash-lib. Alan has been kind enough to provide a pull request but my current thinking is that I'd like kubetail to stay simple and small and not use any dependencies.


kubetail can take default option values from environment variables matching the option name.
