Layerfile runner objects

Each time you look at the dashboard for a run, you’re looking at a collection of layerfile runners. Each layerfile runner is created by a specific Layerfile, or by a Layerfile being retried.

CI jobs are a collection of Layerfile runners!

​
Example schema

{
  "repository_name": "webappio-example",
  "id": 1,
  "uuid": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
  "status": "SEE_RUNNERS",
  "status_change_time": "2000-01-01 01:23:45.123456 +0000 UTC",
  "calculated_status": "SUCCEEDED",
  "commit_sha": "9abc2ac68d52afe1a5a3fbc724d031af5a397204",
  "branch": "master",
  "merge_branch": "master",
  "run_start_reason": "Manual run created by API",
  "run_start_reason_url": ""
}

​
status vs. calculated_status

CI jobs themselves maintain an internal status which is either:

  • NEW for pending jobs
  • ERROR for jobs that have had some error while initializing (e.g., invalid layerfiles)
  • STARTING_RUNNERS for jobs which are in the process of starting runners
  • SEE_RUNNERS for jobs which have started runners. This status means you must look at the runners themselves to understand the status.

CI jobs also contain a status which is the calculated status of the whole job, looking at the runners. The calculated status is usually what you’ll use to determine the status of an entire run.

The calculated_status of a CI job is one of the following:

  • NEW for pending jobs
  • JOB_ERROR for jobs that have had an internal while initializing (e.g., internal errors in webapp.io occurred when starting this run)
  • BAD_LAYERFILE for jobs that had an invalid Layerfile
  • STARTING_RUNNERS means that runners are in the process of being started for this job.
  • FAILURE means that at least one runner failed (some instruction for that runner is red) - again, there can be multiple Layerfiles per repository and if either fails.
  • RUNNER_CANCELLED means that a user manually cancelled at least one runner
  • RUNNER_ERROR means that at least one runner had an internal error while running
  • RUNNING means that the runner itself is running
  • SUCCEEDED means that the runner succeeded

​
Get most recent CI job for a repository matching a search query

It’s often useful to get the most recent CI job given specific filters. This API endpoint allows for that.

Output:

{
  "status": "ok",
  "job": {
    "repository_name": "webappio-example",
    "id": 3,
    "uuid": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee",
    "status": "SEE_RUNNERS",
    "status_change_time": "2000-01-01 01:23:45.123456 +0000 UTC",
    "calculated_status": "SUCCEEDED",
    "commit_sha": "9abc2ac68d52afe1a5a3fbc724d031af5a397204",
    "branch": "master",
    "merge_branch": "master",
    "run_start_reason": "Manual run created by API",
    "run_start_reason_url": ""
  }
}

— or —

{
  "error": "There are no runs in layerdemo/webappio-example matching the given filters.",
  "status": "error"
}

​
Search Filters

The search query for /search and the main dashboard’s searchbar are the same, and can include:

  1. natural text
  2. ”quoted exact text”
  3. -minus -some -terms that should not appear in the author, commit body, or title of the commit.
  4. repo:(the repository name) to match an exact repository name
  5. branch:(the branch name) to match an exact (case sensitive) branch name
  6. id:(the id) to match an exact run id
  7. status:(status) to match a calculated status
  8. running to match a run which is running
  9. done to match a run which is not running
  10. failed to match a run which has suffered a failure or error
Example query

text to find in commit body "exact text" -layer -ci repo:layer-example-repo branch:main id:10 status:running done running failed

​
Create a CI job for a given repository

Sometimes it’s useful to manually start webapp.io runs (for, e.g., deploying) This endpoint lets you do that.

The input to the POST is optional, but can contain:

  • branch=master to check out the “master” branch. If omitted, we use “master”
  • ref=9abc2ac68d52afe1a5a3fbc724d031af5a397204 to check out a specific commit. If omitted, we use “origin/master”
  • accept_buttons=true to accept any BUTTON instructions in the job (i.e., to deploy automatically)
  • extra - extra data exposed in the run as API_EXTRA, useful for passing arbitrary data in

Output:

{
  "status": "ok",
  "job": {
    "repository_name": "webappio-example",
    "id": 1,
    "status": "NEW",
    "status_change_time": "2020-05-05 05:11:44.17955 +0000 UTC",
    "calculated_status": "NEW",
    "commit_sha": "9abc2ac68d52afe1a5a3fbc724d031af5a397204",
    "branch": "master",
    "merge_branch": "master",
    "run_start_reason": "Manual run created by API",
    "run_start_reason_url": ""
  },
  "url": "https://webapp.io/jobs/github/distributed-containers-inc/webappio-example/1"
}

status can be one of "ok" or "error". If the latter exists, an "error" value will be included with an explanation.
