Scale an Application

POST https://$SCALINGO_API_URL/v1/apps/[:app]/scale

Send a scaling request, the status of the application will be changed to ‘scaling’ for the scaling duration. No other operation is doable until the app status has switched to “running” again.

You can follow the operation progress by following the Location header, pointing to an operation resource.

The request returns the complete formation of containers event those which are not currently scaled.

Parameters

  • containers: Array of the containers you want to scale. Each containers:
    • container.name: Name of the container you want to scale
    • container.amount: Final amount of container of this type
    • container.size (optional): Target size of container (not changed if empty). Container sizes list.

Free Usage Limit

You can only have 1 small or medium ‘web’ container without having defined a payment method.

Limit

There is a hard limit of 10 containers of a given type per application, if you need more: contact us

Example request

curl -H "Accept: application/json" -H "Content-Type: application/json" \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X POST 'https://$SCALINGO_API_URL/v1/apps/example-app/scale' -d \

}

Restart an Application

POST https://$SCALINGO_API_URL/v1/apps/[:app]/restart

In the same spirit than the ‘scale’ operation, the restart is an asynchronous operation

Send a restart request, the status of the application will be changed to ‘restarting’ for the operation duration. No other operation is doable until the app status has switched to “running” again.

You can follow the operation progress by following the Location header, pointing to an operation resource.

Parameters

Run a One-off Container

Endpoint used by scalingo run

POST https://$SCALINGO_API_URL/v1/apps/[:app]/run

To run a batch job, or an administrative task, you have to start a one-off container. It is a container you can start for a given task and which will be destroyed after it. It can be any command which will be executed in the environment of your application.

Parameters

  • command (string required): Command line which has to be run (example: “bash”)
  • env (object): Environment variables to inject into the container (additionally to those of your apps)
  • size (string, default "M"): Size of the container (e.g. S, M, etc)
  • detached (boolean, default false): Foreground task by default, set to true if the container has to be run in background.

For one-off started with the parameter detached to false:
You can follow the operation progress by following the Location header, pointing to an operation resource.

Background vs Foreground One-off

By default one-off containers are started as attached command. They will only get started when a terminal interactively connect to it through the one-off endpoint. Once attached, data should be sent to the one-off or from it, otherwise the connection will be automatically closed after 30 minutes and the container stopped. So for long interactive jobs, make sure the process is writing something to stdout or stderr.

If the detached option is set to true, the container starts as a background one-off container. In this case the container is started instantly logs from the job are aggregated to the total logs of the application. You have to make sure this job ends at some point.

Limit

There is a hard limit of 10 containers per application and 50 per account as stated in our documentation. If you need more: contact us

Example request:

curl -H "Accept: application/json" -H "Content-Type: application/json" \

Stop a Container

Endpoint used by scalingo one-off-stop.

POST https://$SCALINGO_API_URL/v1/apps/[:app]/containers/[:container_id]/stop

Asynchronously stops a running container. Only one-off containers can be stopped that way.

You may have started a one-off container in background. This is also called a detached one-off. This endpoint will trigger an asynchronous stop of the one-off container. The container state becomes stopping after it returns but the container is not instantly stopped. It follows the standard container shutdown lifecycle

Example request:

curl -H "Accept: application/json" -H "Content-Type: application/json" \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X POST 'https://$SCALINGO_API_URL/v1/apps/example-app/containers/6054bcc56d80de00682f7a18/stop'

Returns 202 Accepted

List Child Apps of an Application

This endpoint let you list the different child apps of an application

This endpoint supports pagination.

Example

curl -H "Accept: application/json" -H "Content-Type: application/json" \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X GET https://$SCALINGO_API_URL/v1/apps/example-parent-app/child_apps

Returns 201 Created

{
  "child_apps": [
    {
      "created_at":"2017-03-10T18:20:39.454+01:00",
      "id":"58c2d99563b9fe00019298e2",
      "name":"example-child-app-1",
      "parent_app_name": "example-parent-app",
      ...
    }, {
      "created_at":"2017-03-10T18:20:39.454+01:00",
      "id":"58c2d99563b9fe00019298e3",
      "name":"example-child-app-2",
      "parent_app_name": "example-parent-app",
      ...
    }
  ]
}

The recommended value endpoint let you get the value we recommend to use for the autoscaling.

GET https://$SCALINGO_API_URL/v1/stats/:metrics/recommended_value

The metrics are aggregated by container types. If a type have more than one container and the container index is not passed, it returns the mean value of all the containers of the same type. The explanation about this value is in the documentation.

The metrics available are:

  • cpu
  • memory
  • swap
  • 5XX: amount of request which returns a 5XX HTTP status code, indicating a server error
  • all: requests per minute (RPM)
  • rpm_per_container: RPM per container
  • p95_response_time: 95th percentile of the requests response time

Parameters

When querying a metric about resource consumption (CPU, memory and swap), one must also provide the name of the container type of interest:

  • container_type: e.g. web, clock

Example request

curl -H 'Accept: application/json' -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X GET https://$SCALINGO_API_URL/v1/apps/example-app/stats/cpu/recommended_value?container_type=web

Returns 200 OK

}

Get Metrics Data of an Application

The stats endpoint lets you get metrics about the containers of an application. These data include the CPU usage and the memory usage, split between RAM and Swap memory. But also the number of request per minute handled by your app.

GET https://$SCALINGO_API_URL/v1/stats/:metrics(/:container)(/:index)

The metrics are aggregated by container types. If a type have more than one container and the container index is not passed, it will return the mean value of all the containers of the same type.

The metrics available are:

  • cpu
  • memory
  • swap
  • router

If the metrics type is router the container and index parameters are ignored. But you can pass a status_code get variable which filters router metrics by their status code.

Possible values are:

  • 1XX
  • 2XX
  • 3XX
  • 4XX
  • 5XX
  • all

Parameters

  • since: Viewing period in hour

Example request

curl -H 'Accept: application/json' -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X GET https://$SCALINGO_API_URL/v1/apps/example-app/stats/cpu/web/1?since=48

Returns 200 OK

Get Real Time Stats of an Application

To get real time metrics, you can use the following endpoint:

GET https://$SCALINGO_API_URL/v1/apps/[:app]/stats

Return the list of all stats for each container of the application.

Example request

curl -H 'Accept: application/json' -H 'Content-Type: application/json' \
  -H "Authorization: Bearer $BEARER_TOKEN" \
  -X GET https://$SCALINGO_API_URL/v1/apps/example-app/stats

Returns 200 OK
