execute docker command in javascript

To execute docker commands in JavaScript, we can use the Child Process module that is available in Node.js. This module allows us to spawn new processes and communicate with them through stdin, stdout, and stderr streams.

Here is an example on how to start a Docker container and run shell commands within it from JavaScript:

index.tsx
const { spawn } = require('child_process');

// Start a Docker container
const dockerRun = spawn('docker', ['run', '-it', 'ubuntu', '/bin/bash']);

// Log the output from the container
dockerRun.stdout.on('data', (data) => {
  console.log(`stdout: ${data}`);
});

// Log errors from the container
dockerRun.stderr.on('data', (data) => {
  console.error(`stderr: ${data}`);
});

// Run shell commands inside the container
dockerRun.stdin.write('ls\n');
dockerRun.stdin.write('echo "Hello, world!"\n');

// Stop the container
dockerRun.stdin.write('exit\n');

This script spawns a new process that runs the docker run command to start a new ubuntu container and open a /bin/bash shell inside it. We then log the output and errors from the container, and run some shell commands inside it (ls and echo "Hello, world!"). Finally, we stop the container by writing exit to its stdin stream.

Note that in order to use this script, you must have Docker installed on your system and running.
