Struct CmdBuilder 

pub struct CmdBuilder {
    pub command: String,
    pub params: Option<Vec<String>>,
}

Builder struct for CMD instruction (shell form)

• CmdBuilder constructs the shell form for CMD by default. To construct the exec form or CMD in combination with ENTRYPOINT, use CmdExecBuilder.

Format according to Dockerfile reference:

• CMD command param1 param2

Example:

// build CMD by adding multiple params
let cmd = CmdBuilder::builder()
    .command(r#"echo "this is a test""#)
    .param("| wc")
    .param("-l")
    .build().unwrap();
assert_eq!(cmd.to_string(), r#"CMD echo "this is a test" | wc -l"#);

// build CMD with multiple params using a vec    
let cmd = CmdBuilder::builder()
    .command(r#"echo "this is a test""#)
    .params(vec!["| wc", "-l"])
    .build().unwrap();
assert_eq!(cmd.to_string(), r#"CMD echo "this is a test" | wc -l"#);

Fields

command: String

params: Option<Vec<String>>
