This code defines a function getIdentityServer that automates the process of building, running, and managing a Docker container for an identity server, ensuring a fresh container is used each time.

Run example

npm run import -- "set up identity server"

set up identity server

var path = require('path');
// TODO: fix mono build step
var execSync = require('child_process').execSync;
var getIdentityServer = (name = 'act-identity') => {
    var DOCKERFILE = path.resolve(__dirname);
    return identityDockerfile(DOCKERFILE)
        .then(r => execSync('docker build -t ' + name + ' "' + DOCKERFILE + '"').toString())
        .then(r => {
            var ps = execSync('docker ps -a').toString();
            if (ps.indexOf(name) !== -1) {
                return r
                    + execSync('docker stop ' + name).toString()
                    + execSync('docker rm ' + name).toString();
            }
            return '';
        })
        .then(r => r + execSync('docker run --name ' + name + ' ' + name).toString())
        // wait for process to start
        .then(() => new Promise((resolve, reject) =>
            setTimeout(resolve, 5000)));
};
(getIdentityServer);

const path = require('path');
const { execSync } = require('child_process');

This code defines a function getIdentityServer that builds and runs a Docker container for an identity server.

Here's a breakdown:

1. Dependencies:

   • path: Used for working with file paths.
   • child_process: Used to execute shell commands.

2. getIdentityServer Function:

   • Takes an optional name parameter (defaults to 'act-identity') for the container name.
   • DOCKERFILE: Sets the path to the Dockerfile.
   • identityDockerfile(DOCKERFILE): Calls a function (not shown) likely to perform some preparation based on the Dockerfile.

3. Docker Build:

   • execSync('docker build -t ' + name + ' "' + DOCKERFILE + '"'): Builds the Docker image with the specified name.

4. Container Management:

   • Checks if a container with the given name already exists.
   • If it exists, stops and removes the existing container.

5. Container Run:

   • execSync('docker run --name ' + name + ' ' + name): Runs the container with the specified name.

6. Wait for Startup:

   • Uses setTimeout to wait for 5 seconds to allow the container to start before resolving the promise.

7. Return Value:

   • Returns a string containing the output of the Docker commands.

8. Function Call:

   • (getIdentityServer): Immediately calls the getIdentityServer function.

In essence, this code automates the process of building, running, and managing a Docker container for an identity server.
