Codefresh API

How to integrate Codefresh with other systems

Codefresh offers a comprehensive API that you can use to integrate with any other application or solution you already have.

The full details of the API are documented at https://g.codefresh.io/api/

Using the Codefresh API

You can use the API in various ways:

The Codefresh API is updated when new features are added in the Codefresh platform so you can expect any new functionality to appear to the API as well.

Ways to use the Codefresh API

There are several ways to use the API. Some of the most popular ones are:

  1. Triggering builds from another system. You can start a Codefresh pipeline from any other internal system that you already have in your organization.
  2. Getting the status of builds in another system.
  3. Creating pipelines externally. You don’t have to use the Codefresh GUI to create pipelines. You can create them programmatically using your favorite template mechanism. You can reuse pipelines using your own custom implementation if you have special needs in your organization.

You can browse the current API at https://g.codefresh.io/api/.

For each call you will also see an example with curl.

Authentication instructions

Before you can use the API from your application you need an authentication key that will give programmatic access to Codefresh from an external application.

In order to create your own API key, click User Settings on the left sidebar and scroll down until you find the API Keys section. Click the generate button and copy your key.

From the same screen you can also revoke keys if you don’t need them anymore.

Access scopes

The following resources can be targeted with the API:

The scopes available for each resource, are different depending on the type of the resource. Check the ones that you wish to use with this key.

Using the API Key with the Codefresh CLI

Once you have the key use it in the Codefresh Cli like this

codefresh auth create-context --api-key <your_key_here>

Now the Codefresh CLI is fully authenticated. The key is stored in ~/.cfconfig so you only need to run this command once. The CLI can also work with multiple authentication contexts so it is possible to manage multiple Codefresh accounts at the same time.

Example - Triggering pipelines

You can trigger any pipeline in Codefresh and even pass extra environment variables (even if they are not declared in the UI)

Triggering a pipeline via the Codefresh CLI

codefresh run kostis-codefresh/nestjs-example/ci-build -b master -t nestjs-example-trigger-name

You can pass extra environment variables as well:

codefresh run kostis-codefresh/nestjs-example/ci-build -b master -t nestjs-example-trigger-name -v sample-var1=sample1 -v SAMPLE_VAR2=SAMPLE2

For the API you can trigger a pipeline by finding its serviceId from the UI

curl 'https://g.codefresh.io/api/builds/5b1a78d1bdbf074c8a9b3458' --compressed -H 'content-type:application/json; charset=utf-8' -H 'Authorization: <your_key_here>' --data-binary '{"serviceId":"5b1a78d1bdbf074c8a9b3458","type":"build","repoOwner":"kostis-codefresh","branch":"master","repoName":"nestjs-example"}'

You can also pass extra environment variables using an array

curl 'https://g.codefresh.io/api/builds/5b1a78d1bdbf074c8a9b3458' --compressed -H 'content-type:application/json; charset=utf-8' -H 'Authorization: <your_key_here>' --data-binary '{"serviceId":"5b1a78d1bdbf074c8a9b3458","type":"build","repoOwner":"kostis-codefresh","branch":"master","repoName":"nestjs-example","variables":{"sample-var1":"sample1","SAMPLE_VAR2":"SAMPLE2"}}'

Example - getting status from builds

You can get the status of a build from the cli by using its ID:

codefresh get builds 5b4f927dc70d080001536fe3

Same thing with the API

curl -X GET --header "Accept: application/json" --header "Authorization: <your_key_here>" "https://g.codefresh.io/api/builds/5b4f927dc70d080001536fe3"

Example - creating Codefresh pipelines externally

Codefresh has a great UI for creating pipelines for each of your projects. If you wish, you can also create pipelines programmatically in an external manner. This allows you to use your own templating solution for re-using pipelines and creating them from an external system.

First you need a yaml file that defines the pipeline. This is a pipeline specification.

It is also very to create a a dummy pipeline in the Codefresh Web UI and then get its specification by running codefresh get pipeline my-project/my-pipeline -o yaml > my-pipeline-spec.yml

Here is an example

Pipeline Spec

version: '1.0'
kind: pipeline
metadata:
  name: my-project/my-basic-pipeline
  description: my description
  labels:
    key1: value1
    key2: value2
  deprecate:
    applicationPort: '8080'
  project: my-project
spec:
  triggers:
    - type: git
      provider: github
      name: my-trigger
      repo: kostis-codefresh/nestjs-example
      events:
        - push
      branchRegex: /./
  contexts: []
  variables:
    - key: PORT
      value: 5000
      encrypted: false
    - key: SECRET
      value: "secret-value"
      encrypted: true
  steps:
    main_clone:
      title: Cloning main repository...
      type: git-clone
      repo: '${{CF_REPO_OWNER}}/${{CF_REPO_NAME}}'
      revision: '${{CF_REVISION}}'
      git: github-1
    PrintFileList:
      title: Listing files
      image: 'alpine:latest'
      commands:
        - ls -l
  stages: []

Save this spec into a file with an arbitrary name like my-pipeline-spec.yml. First create the new project (if it doesn’t exist already):

codefresh create project my-project

Then you can create the pipeline with the cli

codefresh create pipeline -f my-pipeline-spec.yml

And your pipeline will be available in the GUI

Created Pipeline

New pipeline created

Notice that you must prefix the name of the pipeline with your username and repository so that it becomes visible in the GUI under the correct project.

Using Codefresh from within Codefresh

The Codefresh CLI is also packaged in a Docker image on its own. This makes it very easy to use it from within Codefresh in a free style step.

For example, you can easily call pipeline B from pipeline A
with the following step:

codefresh.yml of pipeline A

version: '1.0'
steps:
  myTriggerStep:
    title: triggering another pipeline
    image: codefresh/cli
    commands:
      - 'codefresh run <pipeline_B> -b=${{CF_BRANCH}}' -t <pipeline-b-trigger-name>
    when:
      condition:
        all:
          validateTargetBranch: '"${{CF_PULL_REQUEST_TARGET}}" == "production"'
          validatePRAction: '''${{CF_PULL_REQUEST_ACTION}}'' == ''opened'''

This step only calls pipeline B when a pull request is opened for the branch named production.

Note that when you use the Codefresh CLI in a pipeline step, it is already configured, authenticated and ready for use. No additional authentication is required.
