About remotefs-kube ☁️

remotefs client implementation for Kube.

Get started

First of all you need to add remotefs and the client to your project dependencies:

remotefs = "^0.3"
remotefs-kube = "^0.4"

these features are supported:

• find: enable find() method for RemoteFs. (enabled by default)
• no-log: disable logging. By default, this library will log via the log crate.

The library provides two different clients:

• KubeMultiPodFs client
• KubeContainerFs client

Kube multi pod client

The MultiPod client gives access to all the pods with their own containers in a namespace.

This client creates an abstract file system with the following structure

• / (root)
  • pod-a
    • container-a
      • / (container-a root)
        • /bin
        • /home
        • ...
    • container-b
      • / (container-b root)
        • ...
  • pod-b
    • container-c
      • / (container-c root)
        • ...

So paths have the following structure: /pod-name/container-name/path/to/file.

// import remotefs trait and client
use remotefs::RemoteFs;
use remotefs_kube::KubeMultiPodFs;
use std::path::Path;

let rt = Arc::new(
    tokio::runtime::Builder::new_current_thread()
    .enable_all()
    .build()
    .unwrap(),
);
let mut client: KubeMultiPodFs = KubeMultiPodFs::new(&rt);

// connect
assert!(client.connect().is_ok());
// get working directory
println!("Wrkdir: {}", client.pwd().ok().unwrap().display());
// change working directory
assert!(client.change_dir(Path::new("/my-pod/alpine/tmp")).is_ok());
// disconnect
assert!(client.disconnect().is_ok());

Kube container client

Here is a basic usage example, with the KubeContainerFs client, which is used to connect and interact with a single container on a certain pod. This client gives the entire access to the container file system.

// import remotefs trait and client
use remotefs::RemoteFs;
use remotefs_kube::KubeContainerFs;
use std::path::Path;

let rt = Arc::new(
    tokio::runtime::Builder::new_current_thread()
    .enable_all()
    .build()
    .unwrap(),
);
let mut client: KubeContainerFs = KubeContainerFs::new("my-pod", "container-name", &rt);

// connect
assert!(client.connect().is_ok());
// get working directory
println!("Wrkdir: {}", client.pwd().ok().unwrap().display());
// change working directory
assert!(client.change_dir(Path::new("/tmp")).is_ok());
// disconnect
assert!(client.disconnect().is_ok());

Client compatibility table ✔️

The following table states the compatibility for the client client and the remote file system trait method.

Note: connect(), disconnect() and is_connected() MUST always be supported, and are so omitted in the table.

append	No
change_dir	Yes
copy	Yes
create_dir	Yes
create_file	Yes
