Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

# Gawk version
# Remote
grep -v "rem_address" /proc/net/tcp  | awk  '{x=strtonum("0x"substr($3,index($3,":")-2,2)); for (i=5; i>0; i-=2) x = x"."strtonum("0x"substr($3,i,2))}{print x":"strtonum("0x"substr($3,index($3,":")+1,4))}'

# Local
grep -v "rem_address" /proc/net/tcp | awk  '{x=strtonum("0x"substr($2,index($2,":")-2,2)); for (i=5; i>0; i-=2) x = x"."strtonum("0x"substr($2,i,2))}{print x":"strtonum("0x"substr($2,index($2,":")+1,4))}'

# No Gawk

grep -v "rem_address" /proc/net/tcp  | awk 'function hextodec(str,ret,n,i,k,c){

Applicability

The instructions below apply to older versions of Homebrew which still provide switch capability.

For current Homebrew, you'll likely need to keep Versions around, and build locally. Here's my versions repository https://github.com/rdump/homebrew-versions

MacPorts is now keeping versioned installations available as well, by default.

Helm 3 is storing description of it's releases in secrets. You can simply find them via

$ kubectl get secrets
NAME                                                TYPE                                  DATA   AGE
sh.helm.release.v1.wordpress.v1                     helm.sh/release.v1                    1      1h

If you want to get more info about the secret, you can try to describe the secret

$ kubectl describe secret sh.helm.release.v1.wordpress.v1
