Redis

Create a Pipeline with a Redis service dependency.

This guide covers configuring continuous integration pipelines for projects that have a Redis dependency.

Basic Example

In the below example we demonstrate a pipeline that launches Redis as a background step. The database server will be available at redis:6379, where the hostname matches the background step name.

kind: pipeline
spec:
  stages:
  - type: ci
    spec:
      steps:
      - name: redis
        type: background
        spec:
          container: redis

      - name: test
        type: run
        spec:
          container: redis
          script: |-
            sleep 5
            redis-cli -h redis ping
            redis-cli -h redis set FOO bar
            redis-cli -h redis get FOO

Common Problems

Initialization

If you are unable to connect to the Redis container please make sure you are giving Redis adequate time to initialize and begin accepting connections.

      - name: test
        type: run
        spec:
          container: redis
          script: |-
            sleep 5
            redis-cli -h redis ping

Incorrect Hostname

You cannot use 127.0.0.1 or localhost to connect with the Redis container. If you are unable to connect to the Redis container please verify you are using the correct hostname, corresponding with the name of the redis service container.

Bad:

      - name: test
        type: run
        spec:
          container: redis
          script: |-
            sleep 5
            redis-cli -h localhost ping

Good:

      - name: test
        type: run
        spec:
          container: redis
          script: |-
            sleep 5
            redis-cli -h redis ping
