Working with stacks

Working with Stacks

In Nebula, a collection of services is called Stack.

stack {
    http {
        get("/hello") { call ->
            call.respondText("Hello, World!")
    }
}

Stacks are managed by submitting to a Nebula server over http:

Creating a stack

Create a stack by POSTing a Nebula script to /stacks

curl --location 'http://localhost:8099/stacks' \
--header 'Content-Type: text/plain' \
--data 'stack {
    http {
        get("/hello") { call ->
            call.respondText("Hello, World!")
        }
    }
}'

Listing the state of current stacks

Fetch the current stacks (including their configured variables) by GET /stacks

curl --location 'http://localhost:8099/stacks'
