Circle CI Actions

Port's Circle CI Action can trigger a new pipeline using a customer provided input and port_payload.

Port Kafka Architecture

The steps shown in the image above are as follows:

  1. Port publishes an invoked Action message containing the pipeline details to a topic;
  2. A secure topic (ORG_ID.runs) holds all the action invocations;
  3. Port's execution agent pulls the new trigger event from your Kafka topic, and triggers your Circle CI pipeline.

Prerequisites

  • Helm must be installed to use the chart. Please refer to Helm's documentation for further details on the installation;
  • The connection credentials to Kafka are provided to you by Port;
  • If you want to trigger a Circle CI pipeline, you need to have a Circle CI personal API token.

Further steps

Triggering example

Create the following blueprint, action and mapping to trigger a Circle CI pipeline.

Blueprint
{
"identifier": "circle_ci_project",
"title": "CircleCI Project",
"icon": "CircleCI",
"schema": {
"properties": {
"project_slug": {
"title": "Slug",
"type": "string"
}
},
"required": ["project_slug"]
},
"mirrorProperties": {},
"calculationProperties": {},
"relations": {}
}
Action
[
{
"identifier": "trigger_circle_ci_pipeline",
"title": "Trigger CircleCI pipeline",
"icon": "CircleCI",
"userInputs": {
"properties": {},
"required": [],
"order": []
},
"invocationMethod": {
"type": "WEBHOOK",
"agent": true,
"synchronized": false,
"method": "POST",
"url": "https://circleci.com"
},
"trigger": "DAY-2",
"requiredApproval": false
}
]
Mapping - (Should be saved as a file named invocations.json)
info

To read more about the controlThePayload configuration, please refer to the Control the payload documentation.

[
{
"enabled": ".action == \"trigger_circle_ci_pipeline\"",
"url": "(env.CIRCLE_CI_URL // \"https://circleci.com\") as $baseUrl | .payload.entity.properties.project_slug | @uri as $path | $baseUrl + \"/api/v2/project/\" + $path + \"/pipeline\"",
"headers": {
"Circle-Token": "env.CIRCLE_CI_TOKEN"
},
"body": {
"branch": ".payload.properties.branch // \"main\"",
"parameters": ".payload.action.invocationMethod as $invocationMethod | .payload.properties | to_entries | map({(.key): (.value | tostring)}) | add | if $invocationMethod.omitUserInputs then {} else . end"
}
}
]

Installation

  1. Add Port's Helm repo by using the following command:
helm repo add port-labs https://port-labs.github.io/helm-charts
note

If you already added this repo earlier, run helm repo update to retrieve the latest versions of the charts. You can then run helm search repo port-labs to see the charts.

  1. Create a JSON file named invocations.json with the mapping above.

  2. Install the port-agent chart by using the following command after filling in the required values:

helm install my-port-agent port-labs/port-agent \
--create-namespace --namespace port-agent \
--set-file controlThePayloadConfig=./invocations.json \
--set env.normal.PORT_ORG_ID=YOUR_ORG_ID \
--set env.normal.KAFKA_CONSUMER_GROUP_ID=YOUR_KAFKA_CONSUMER_GROUP \
--set env.secret.PORT_CLIENT_ID=YOUR_PORT_CLIENT_ID \
--set env.secret.PORT_CLIENT_SECRET=YOUR_PORT_CLIENT_SECRET \
--set env.secret.CIRCLE_CI_TOKEN=YOUR_CIRCLE_CI_PERSONAL_TOKEN
