但是，如果使用此选项，容器将不再运行其默认的ENTRYPOINT或CMD命令，因为entrypoint:会覆盖默认命令。
volumes: - ./wait-for-it.sh:/wait-for-it.sh 在上面的配置中,我们将wait-for-it.sh脚本添加到web服务的容器中,并通过command指令设置容器的启动命令。启动命令中,我们首先使用wait-for-it.sh脚本等待db服务的3306端口可用,然后等待redis服务的6379端口可用。最后,当两个依赖服务都可用时,我们启动nginx服务。...
>wait-for-it.sh host_name : 3306 -- catalina.sh run 下面介绍使用 command 指令 + wait-for-it 脚本 来做 启动依赖 启动依赖 最后一点就是需要用把 wait-for-it.sh打包到镜像中 ===Dockerfile=== FROM tomcat:latest COPY ./wait-for-it.sh /usr/local/tomcat/bin/ === 完整代码见: https://...
从上面的pom.xml可见,我们将Java应用制作成docker镜像时,使用的基础镜像是openjdk:8-jdk-stretch,这样做出的应用镜像是不含wait-for-it.sh脚本的,自然就无法实现启动顺序控制了,因此我们要做一个带有wait-for-it.sh的基础镜像给业务镜像用: 把wait-for-it.sh文件准备好,下载地址:https://raw.githubusercontent...

Sometimes pgweb starts before Postgres, and it fails, because Postgres is slower to start, or it has to initialize its database or recover. This makes it try until Postgres is available. Two commit...
Let’s talk about Dockerfile efficiency – something I’ve wrestled with more times than I can count. Back in the day, Docker builds could feel like a slow dance. You make a small change in your code, and wait for what feels like an eternity for the build to complete. It was a fr...
