CircleCI 2.0 改版看起來是簡單一點，文件也比較齊全，就把編譯指令改成2.0的吧
首先是原本專案目錄下的 circle.yml 不再用這個位置了
改成放在 .circleci/config.yml
內容如下 (cache部分改天再研究看看)
version: 2
jobs:
build:
working_directory: ~/test-rest
docker:
- image: circleci/openjdk:8-jdk
steps:
- checkout
- setup_remote_docker
# - restore_cache:
# key: circleci-demo-java-spring-{{ checksum "pom.xml" }}
#
# - run: mvn dependency:go-offline
#
# - save_cache:
# paths:
# - ~/.m2
# key: circleci-demo-java-spring-{{ checksum "pom.xml" }}
- run: gradle build
- store_test_results:
path: target/surefire-reports
- store_artifacts:
path: build/libs/test-rest-0.0.1-SNAPSHOT.jar
- run:
name: build and push Docker image
command: |
TAG=0.1.$CIRCLE_BUILD_NUM
docker build -t spike234/test-rest:$TAG .
docker login -u $DOCKER_USER -p $DOCKER_PASS
docker push spike234/test-rest:$TAG
不用更新 Gradle 版本就可以正常編譯了
編譯 Docker Image 的 Dockerfile 如下
FROM java:8
label maintainer "spike19820318@gmail.com"
ADD build/libs/test-rest-0.0.1-SNAPSHOT.jar app.jar
EXPOSE 8080
ENV JAVA_OPTS=""
ENTRYPOINT ["java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "app.jar"]
指令也改成用 ENTRYPOINT
好吧~~就這樣簡單，來去玩 Kubernetes 了
要把這服務放在 Kubernetes 運行
cat << EOF > test-rest.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: test-rest-deployment
spec:
replicas: 1
template:
metadata:
labels:
app: test-rest
spec:
containers:
- name: test-rest
image: spike234/test-rest:0.1.7
ports:
- containerPort: 8080
resources:
requests:
cpu: 100m
EOF
kubectl create -f test-rest.yaml
cat << EOF > test-rest-svc.yaml
apiVersion: v1
kind: Service
metadata:
name: test-rest
labels:
app: test-rest
spec:
type: NodePort
selector:
app: test-rest
ports:
- port: 8080
targetPort: 8080
nodePort: 30080
EOF
kubectl create -f test-rest-svc.yaml
收工~~
