Struct TagCommand 

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

Docker tag command builder

Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE.

Example

use docker_wrapper::TagCommand;

// Tag an image with a new name
TagCommand::new("myapp:latest", "myregistry.com/myapp:v1.0.0")
    .run()
    .await?;

// Tag with just a new tag on the same repository
TagCommand::new("myapp:latest", "myapp:stable")
    .run()
    .await?;

Fields

executor: CommandExecutor

Command executor

Implementations

impl TagCommand

pub fn new( source_image: impl Into<String>, target_image: impl Into<String>, ) -> Self

Create a new tag command

Example

use docker_wrapper::TagCommand;

// Tag an image for a registry
let cmd = TagCommand::new("myapp:latest", "docker.io/myuser/myapp:v1.0");

// Create an alias tag
let cmd = TagCommand::new("nginx:1.21", "nginx:stable");

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

Execute the tag command

Errors

Returns an error if:

• The Docker daemon is not running
• The source image doesn’t exist
• The target image name is invalid

Example

use docker_wrapper::TagCommand;

let result = TagCommand::new("alpine:latest", "my-alpine:latest")
    .run()
    .await?;

if result.success() {
    println!("Image tagged successfully");
}

pub fn get_executor(&self) -> &CommandExecutor

Get a reference to the command executor

pub fn get_executor_mut(&mut self) -> &mut CommandExecutor

Get a mutable reference to the command executor
