Kubernetes Pod File System Explorer and extras VSCode extension

This extension extends the Clusters explorer view provided by Microsoft's Kubernetes extension. It enables viewing of container filesystems and vieweing and copying files to and from the container filesystem. It adds additional commands and additional tree nodes to the Cluster Explorer tree view.

Features

It supports the following commands:

Command	Treenode Type	Description
k8s.node.terminal (Terminal)	Node	Start a shell into Node using nsenter. User must set the kubernetes-file-system-explorer.nsenter-image preference value to point to a nsenter image of choice e.g. jpetazzo/nsenter:latest. Preferably use jpetazzo/nsenter@sha256:9a5758441e7929abcff9f13a69b4ca962063ec89b818395f02b7b7e8150ca088 to use cached image.
k8s.pod.container.terminal (Terminal)	Container	Starts a shell in the Container. It basically runs: kubectl exec -it pod-name -c containername -- sh
k8s.pod.container.folder.find (Find)	Container Folder Node	Show the output of find folderpath in editor. It basically runs: kubectl exec -it pod-name -c containername -- find /path/to/folder
k8s.pod.container.folder.ls-al (ls -al)	Container Folder Node	Show the output of ls -al folderpath in editor. It basically runs: kubectl exec -it pod-name -c containername -- ls -al /path/to/folder
k8s.pod.container.folder.cp-from (kubectl cp from)	Container Folder Node	kubectl cp from FolderNode to a local folder
k8s.pod.container.folder.cp-to-from-folder (kubectl cp to from folder)	Container Folder Node	kubectl cp from a local folder to the FolderNode
k8s.pod.container.folder.cp-to-from-file (ls -al)	Container Folder Node	kubectl cp from a local file to the FolderNode
k8s.pod.container.file.view (View file)	Container File Node	Show the contents of the file in editor. It basically runs: kubectl exec -it pod-name -c containername -- cat /path/to/file
k8s.pod.container.file.tail-f (tail -f)	Container File Node	Tail -f the contents of the file in terminal. It basically runs: kubectl exec -it pod-name -c containername -- tail -f /path/to/file. That way you can tail arbitrary files.
k8s.pod.container.file.cp-from (kubectl cp from)	Container File Node	kubectl cp from FileNode to a local folder

This extension adds tree nodes for the Kubernetes Init Containers, Containers and filesystem of the Kubernetes Containers under the Pod node in the Kubernetes Explorer View. Simply expands the treenode for a Pod to see it's Init Containers, Containers and Container filesystem. For example, the following screenshot shows the:

• the haveged-445n7 pod
• the haveged container
• the haveged container's file system
• View file command in the context menu of /etc/bash.bashrc file
• /etc/bash.bashrc file content loaded in a editor tab

How the file system explorer works

It basically starts at / by running the following Kubectl command in the container to get the file listing:

kubectl exec -it pod-name -c containername -- ls -f /

As the tree nodes for directories are expanded e.g. /etc/, it basically runs:

kubectl exec -it pod-name -c containername -- ls -f /etc/

to get listing of files and created tree nodes for them.

Requirements

This extension works with Microsoft Kubernetes extension.
