kubectl plugin for generating reusable bash functions. This is 2 plugins in one binary:
- jid : bash function to get a single json-path value, wraps
kubectl get -o jsonpath=... - jid-cols : bash function to print a custom table, wraps
kubectl get -o custom-columns=...
In both case the jsonpath is interactively contstructed, with the help of jid (Json Incremental Digger)
If you don't use krew, or just to want quickly try the latest dev version:
curl -Lo /usr/local/bin/kubectl-jid https://github.com/lalyos/jidder/releases/download/tip/jidder-$(uname)-$(uname -m)
chmod +x /usr/local/bin/kubectl-jid
cp /usr/local/bin/kubectl-jid /usr/local/bin/kubectl-jid_cols
First make sure krew is installed
$ kubectl krew version
OPTION VALUE
GitTag v0.4.0
...
Until it gets into the official krew plugin index, it can be isntalled from a custom plugin repo:
$ kubectl krew index add lalyos https://github.com/lalyos/krew-index.git
$ kubectl krew install lalyos/jid
$ kubectl krew install lalyos/jid-cols
To start step-by-step first interactively select the resourceType, and only print the generated helper function
$ kubectl jid
If you know beforhand which resource type you want to work with, you can preselect it as the first argument:
$ kubectl jid node
If you want to use the generated function right away, instead of copy pasting:
$ eval $(kubectl jid)
Lets say you want to create a new table list of nodes with custom columns
$ kubectl jid-cols node
- follow on-screen instructions to add new columns (NAME is by default the first column)
- after each column you will se a preview of the table
As an example you can select 3 columns:
- next column name: ip path:
.items[0].metadata.name - next column name: os path:
.items[0].status.addresses[1].address - next column name: version path:
.items[0].status.nodeInfo.kubeletVersion - next column name: q to quit
kcc-node() { kubectl get node -o custom-columns="NAME:.metadata.name,IP:.status.addresses[1].address,OS:.metadata.labels.kubernetes\.io/os,VERSION:.status.nodeInfo.kubeletVersion" ; }
If you want to use the generated function right away, instead of copy pasting:
$ eval $(kubectl jid)
Altough strictly speaking there are dependencies like:
But they are included in the single binary
Even staic bash is included via go-basher
