Struct HistoryCommand 

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

Docker history command builder

Show the history of an image, including layer information.

Example

use docker_wrapper::HistoryCommand;

// Show image history
let history = HistoryCommand::new("nginx:latest")
    .run()
    .await?;

for layer in history.layers() {
    println!("{}: {} ({})", layer.id, layer.created_by, layer.size);
}

Fields

executor: CommandExecutor

Command executor

Implementations

impl HistoryCommand

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

Create a new history command

Example

use docker_wrapper::HistoryCommand;

let cmd = HistoryCommand::new("nginx:latest");

pub fn human(self, human: bool) -> Self

Show human readable sizes

Example

use docker_wrapper::HistoryCommand;

let cmd = HistoryCommand::new("nginx:latest")
    .human(true);

pub fn no_trunc(self, no_trunc: bool) -> Self

Don’t truncate output

Example

use docker_wrapper::HistoryCommand;

let cmd = HistoryCommand::new("nginx:latest")
    .no_trunc(true);

pub fn quiet(self, quiet: bool) -> Self

Show quiet output (only image IDs)

Example

use docker_wrapper::HistoryCommand;

let cmd = HistoryCommand::new("nginx:latest")
    .quiet(true);

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

Format output using a Go template

Example

use docker_wrapper::HistoryCommand;

let cmd = HistoryCommand::new("nginx:latest")
    .format("{{.ID}}: {{.CreatedBy}}");

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

Execute the history command

Errors

Returns an error if:

• The Docker daemon is not running
• The image doesn’t exist

Example

use docker_wrapper::HistoryCommand;

let result = HistoryCommand::new("nginx:latest")
    .run()
    .await?;

if result.success() {
    println!("Image layers:");
    for layer in result.layers() {
        println!("{}: {}", layer.id, layer.size);
    }
}
