构建OSM转MATSim的Docker镜像时遇java:8镜像找不到错误求助

原Dockerfile内容 #

FROM java:8
RUN mkdir /osm2matsim
WORKDIR /osm2matsim

COPY . . 
RUN javac -cp vendor/matsim-0.9.0/matsim-0.9.0.jar Osm2matsim.java

ENTRYPOINT ["java", "-cp", "vendor/matsim-0.9.0/matsim-0.9.0.jar:.", "Osm2matsim"]

解决方案 #

• 替换废弃的基础镜像：java:8是Docker Hub上旧的官方Java镜像，现已被移除归档，无法拉取。改用官方维护的OpenJDK镜像，推荐两个选项：

  • openjdk:8-jdk-alpine：轻量Alpine版本，镜像体积小，适合生产环境
  • eclipse-temurin:8-jdk：Adoptium维护的标准JDK，兼容性更强

• 修改后的Dockerfile示例（以openjdk:8-jdk-alpine为例）：

FROM openjdk:8-jdk-alpine
RUN mkdir /osm2matsim
WORKDIR /osm2matsim

COPY . . 
RUN javac -cp vendor/matsim-0.9.0/matsim-0.9.0.jar Osm2matsim.java

ENTRYPOINT ["java", "-cp", "vendor/matsim-0.9.0/matsim-0.9.0.jar:.", "Osm2matsim"]

• 重新构建镜像：执行修正后的构建命令（原命令末尾多了一个冗余的.，已去掉）：

docker build . -t osm-to-matsim
