Using shared Mountpoint with Drone pipelines

Drone Support

A shared mountpoint can be useful in Drone pipelines when you want to share data or files between different pipeline steps or between the pipeline and the host machine. To use a shared mountpoint in your Drone pipelines, you can follow these steps:

  1. Create a Kubernetes persistent volume:

You can use a Kubernetes persistent volume to create a shared mountpoint that can be accessed by different pipeline steps. Here’s an example persistent volume manifest:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: shared-data
spec:
  accessModes:
    - ReadWriteOnce
  capacity:
    storage: 1Gi
  hostPath:
    path: /mnt/shared-data

In this example, the persistent volume is created using a hostPath that points to a directory on the host machine (/mnt/shared-data).

  1. Create a Kubernetes persistent volume claim:

You can use a Kubernetes persistent volume claim to request a persistent volume and use it as a shared mountpoint in your pipeline steps. Here’s an example persistent volume claim manifest:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: shared-data-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  volumeName: shared-data

In this example, the persistent volume claim requests a persistent volume of size 1Gi with ReadWriteOnce access mode and specifies the name of the persistent volume created in the previous step.

  1. Mount the shared mountpoint in your pipeline steps:

You can mount the shared mountpoint in your pipeline steps by specifying the persistent volume claim as a volume and using it in your container’s volume mounts. Here’s an example pipeline step manifest:

kind: pipeline
name: my-pipeline
steps:
  - name: step1
    image: alpine
    commands:
      - echo "Hello from step1!"
    volumeMounts:
      - name: shared-data
        mountPath: /mnt/shared-data
  - name: step2
    image: alpine
    commands:
      - echo "Hello from step2!"
    volumeMounts:
      - name: shared-data
        mountPath: /mnt/shared-data
volumes:
  - name: shared-data
    persistentVolumeClaim:
      claimName: shared-data-claim

In this example, the shared mountpoint is mounted in both pipeline steps by specifying the name of the persistent volume claim as a volume in the pipeline and using it in the container’s volume mounts.

By using a shared mountpoint in your Drone pipelines, you can easily share data or files between different pipeline steps or between the pipeline and the host machine.
