In this coding challenge we kindly ask you to implement a rather contrived HTTP job processing service. A job is a collection of tasks, where each task has a name and a shell command. Tasks may depend on other tasks and require that those are executed beforehand. The service takes care of sorting the tasks to create a proper execution order. An example request body:
{
"tasks": [
{
"name": "task-1",
"command": "touch /tmp/file1"
},
{
"name": "task-2",
"command": "cat /tmp/file1",
"requires": ["task-3"]
},
{
"name": "task-3",
"command": "echo 'Hello World!' > /tmp/file1",
"requires": ["task-1"]
},
{
"name": "task-4",
"command": "rm /tmp/file1",
"requires": ["task-2", "task-3"]
}
]
}For which an example response might look like the following:
{
"tasks": [
{
"name": "task-1",
"command": "touch /tmp/file1"
},
{
"name": "task-3",
"command": "echo 'Hello World!' > /tmp/file1"
},
{
"name": "task-2",
"command": "cat /tmp/file1"
},
{
"name": "task-4",
"command": "rm /tmp/file1"
}
]
}Additionally, the service should be able to return a bash script representation directly:
#!/usr/bin/env bash
touch /tmp/file1
echo "Hello World!" > /tmp/file1
cat /tmp/file1
rm /tmp/file1
