docker 运行并使用 arthas 的方式

docker run --init

FROM openjdk:8-jdk-alpine

# copy arthas
COPY --from=hengyunabc/arthas:latest /opt/arthas /opt/arthas

ENV LOG_PATH=/opt/logs \
    LOG_HOME=/opt/logs/backup

RUN mkdir -p /opt/logs/backup && \
    mkdir -p /opt/apps

ADD target/*.jar /opt/apps/

EXPOSE 8080

ENTRYPOINT ["java", "-XX:+UseG1GC", "-jar", "/opt/apps/spring-boot-demo.jar"]

安装tini

FROM openjdk:8-jdk-alpine

# copy arthas
COPY --from=hengyunabc/arthas:latest /opt/arthas /opt/arthas

ENV LOG_PATH=/opt/logs \
    LOG_HOME=/opt/logs/backup

RUN mkdir -p /opt/logs/backup && \
    mkdir -p /opt/apps && \
    apk add --no-cache tini

ADD target/*.jar /opt/apps/

EXPOSE 8080

ENTRYPOINT ["/sbin/tini", "--", "java", "-XX:+UseG1GC", "-jar", "/opt/apps/spring-boot-demo.jar"]

使用 sh -c java -jar xxx && 1

FROM openjdk:8-jdk-alpine

# copy arthas
COPY --from=hengyunabc/arthas:latest /opt/arthas /opt/arthas

ENV LOG_PATH=/opt/logs \
    LOG_HOME=/opt/logs/backup

RUN mkdir -p /opt/logs/backup && \
    mkdir -p /opt/apps

ADD target/*.jar /opt/apps/

EXPOSE 8080

ENTRYPOINT ["/bin/sh", "-c", "set -e && java -jar /opt/apps/spring-boot-demo.jar && 1"]

直接使用 hengyunabc/arthas 与 tini 方式类似，镜像已安装 tini

FROM hengyunabc/arthas

ENV LOG_PATH=/opt/logs \
    LOG_HOME=/opt/logs/backup

RUN mkdir -p /opt/logs/backup && \
    mkdir -p /opt/apps

ADD target/*.jar /opt/apps/

EXPOSE 8080

ENTRYPOINT ["/sbin/tini", "--", "java", "-XX:+UseG1GC", "-jar", "/opt/apps/spring-boot-demo.jar"]

注

COPY --from=hengyunabc/arthas:latest /opt/arthas /opt/arthas 只是为了集成 arthas, 可以去除
