```yaml
kind: pipeline
name: publish-mysvc1
steps:
- name: publish

settings:
context: mysvc1
dockerfile: mysvc1/Dockerfile
username:
from_secret: docker_username
password:
from_secret: docker_password
registry: harbor.mycompany.com
repo: harbor.mycompany.com/myuser/mysvc1
tags:
- ${DRONE_COMMIT_BRANCH}-${DRONE_COMMIT_SHA:0:7}
- latest
when:
event: push

---
kind: pipeline
name: publish-mysvc2
steps:
- name: publish
image: plugins/docker
settings:
context: mysvc2
dockerfile: mysvc2/Dockerfile
username:
from_secret: docker_username
password:
from_secret: docker_password

kind: pipeline
name: update-kustomization
steps:
- name: kustomization
pull: if-not-exists
image: minghsu0107/update-kustomization
environment:
SSH_KEY:
from_secret: ssh_key
MANIFEST_HOST: git.mycompany.com
MANIFEST_USER: myuser
MANIFEST_USER_EMAIL: [email protected]
MANIFEST_REPO: myapp-manifests
MANIFEST_BRANCH: main
IMAGES: harbor.mycompany.com/myuser/mysvc1,harbor.mycompany.com/myuser/mysvc2
IMAGE_TAG: ${DRONE_COMMIT_BRANCH}-${DRONE_COMMIT_SHA:0:7}
KUSTOMIZATION: overlays/production
when:
event: push
depends_on:
- publish-mysvc1
- publish-mysvc2
```
In the above example, the image tag is in the form of `${DRONE_COMMIT_BRANCH}-${DRONE_COMMIT_SHA:0:7}`, where `DRONE_COMMIT_BRANCH` and `DRONE_COMMIT_SHA` are environment variables provided by Drone at run time.
