Struct SaveCommand 

pub struct SaveCommand {
    pub executor: CommandExecutor,
    /* private fields */
}

Docker save command builder

Save one or more images to a tar archive (streamed to STDOUT by default).

Example

use docker_wrapper::SaveCommand;
use std::path::Path;

// Save image to file
SaveCommand::new("alpine:latest")
    .output(Path::new("alpine.tar"))
    .run()
    .await?;

// Save multiple images
SaveCommand::new_multiple(vec!["alpine:latest", "nginx:latest"])
    .output(Path::new("images.tar"))
    .run()
    .await?;

Fields

executor: CommandExecutor

Command executor

Implementations

impl SaveCommand

pub fn new(image: impl Into<String>) -> Self

Create a new save command for a single image

Example

use docker_wrapper::SaveCommand;

let cmd = SaveCommand::new("alpine:latest");

pub fn new_multiple(images: Vec<impl Into<String>>) -> Self

Create a new save command for multiple images

Example

use docker_wrapper::SaveCommand;

let cmd = SaveCommand::new_multiple(vec!["alpine:latest", "nginx:latest"]);

pub fn image(self, image: impl Into<String>) -> Self

Add another image to save

pub fn output(self, path: &Path) -> Self

Set output file path

Example

use docker_wrapper::SaveCommand;
use std::path::Path;

let cmd = SaveCommand::new("alpine:latest")
    .output(Path::new("alpine.tar"));

pub async fn run(&self) -> Result<SaveResult>

Execute the save command

Errors

Returns an error if:

• The Docker daemon is not running
• Any of the specified images don’t exist
• Cannot write to the output file

Example

use docker_wrapper::SaveCommand;
use std::path::Path;

let result = SaveCommand::new("alpine:latest")
    .output(Path::new("alpine.tar"))
    .run()
    .await?;

if result.success() {
    println!("Images saved successfully");
}
