Docker 多阶段构建从前一阶段复制失败
Docker Multistage Build Fails on copy from previous stage
我正在处理一个多阶段 docker 构建文件，试图向我们的基础 tomcat 映像添加一个额外的 war 文件。我在 windows 10 工作站上 运行 在本地 Docker 为 Windows 版本 2.3.0.4 使用 docker 引擎版本 19.03.12[=22] =]
我原来的docker文件看起来像这样
FROM tomcat:9.0.21-jdk8-openjdk
RUN rm -rf /usr/local/tomcat/webapps/*
COPY logging.properties /usr/local/tomcat/conf
COPY tomcat-users.xml /usr/local/tomcat/conf
COPY jt400-jdk8-9.7.jar /usr/local/tomcat/lib
COPY mysql-connector-java-8.0.12.jar /usr/local/tomcat/lib
COPY ojdbc6.jar /usr/local/tomcat/lib
COPY hazelcast-all-3.12.jar /usr/local/tomcat/lib
COPY hazelcast-tomcat85-sessionmanager-1.1.3.jar /usr/local/tomcat/lib
COPY hazelcast-client.xml /usr/local/tomcat/lib
COPY applicationinsights-agent-2.5.1.jar /usr/local/tomcat/lib
我想做的是从源代码构建 psi-probe 并将 war 文件添加到此基础映像。
这是我目前所拥有的
FROM maven:3.6.3-openjdk-8 as buildprobe
RUN git clone https://github.com/psi-probe/psi-probe && cd psi-probe
WORKDIR /psi-probe
RUN mvn package && ls -l /psi-probe && ls -l /psi-probe/psi-probe-web/target
FROM tomcat:9.0.21-jdk8-openjdk
RUN rm -rf /usr/local/tomcat/webapps/*
COPY --from=buildprobe /psi-probe/psi-probe-web/taget/probe.war /usr/local/tomcat/webapps
我可以 运行 docker build --target buildprobe -t buildprobe -f Dockerfile . 并且输出已构建。
NOTE: I added the ls commands after mvn package in an attempt to "debug" what going on
maven 包和两个 ls 命令的输出是 (t运行cated)

然而，当构建进入阶段 1 (FROM tomcat:9.0.21-jdk8-openjdk) 时，它在 COPY 命令上失败
COPY failed: stat /var/lib/docker/overlay2/81826a6b59d58818c342f1d5536489f4658be5e8557084ec572780aaf6ea19bc/merged/psi-probe/psi-probe-web/taget/probe.war: no such file or directory
我有一个类似的 docker 文件用于我正在开发的 angular 应用程序。该文件内容如下：
FROM node AS build
WORKDIR /app
ENV PATH /app/node_modules/.bin:$PATH
COPY package.json /app/package.json
RUN npm install && npm install -g @angular/cli
COPY . /app
RUN ng build --output-path=dist
FROM nginx
COPY --from=build /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]
在此文件中，前一阶段的 COPY 工作正常并且图像构建
我只是不确定尝试从源构建 psi-probe 然后将输出包含在我的 tomcat 图像中出了什么问题。
这将完成工作：
FROM maven:3.6.3-openjdk-8 as buildprobe
RUN git clone https://github.com/psi-probe/psi-probe && cd psi-probe

RUN mvn package && ls -l /psi-probe && ls -l /psi-probe/psi-probe-web/target
