构建私有仓库 flink image 镜像

准备flink-*.tar.gz

可以自己编译，或者下载

编译

cd ${flink-root}
mvn install -DskipTests

# 编译成功后，压缩成tar.gz
 cd ./flink-dist/target/
 
 tar -cvf flink-1.18-SNAPSHOT-bin.tar.gz ./flink-1.18-SNAPSHOT-bin

下载

准备 gosu

docker-entrypoint.sh 需要使用到 gosu

https://github.com/tianon/gosu/releases/download/1.11/gosu-amd64
https://github.com/tianon/gosu/releases/download/1.11/gosu-amd64.asc

Dockefile

flink原始的 https://github.com/apache/flink-docker

我这边换了一个底层镜像，其他的都是类似

FROM openjdk:8-jre

ENV FLINK_TAR=flink-1.18-SNAPSHOT.tar.gz
COPY gosu-amd64 /usr/local/bin/gosu
COPY gosu-amd64.asc /usr/local/bin/gosu.asc

  rm -rf "$GNUPGHOME" /usr/local/bin/gosu.asc; \
  chmod +x /usr/local/bin/gosu; \
  gosu nobody true

docker build ./ -t tmaster:5000/flink:1.18-SNAPSHOP

push 到私有仓库

docker push tmaster:5000/flink:1.18-SNAPSHOT

Demo

在flink-conf.yaml修改镜像

kubernetes.container.image.ref: tmaster:5000/flink:1.18-SNAPSHOT

在linux 上启动 kubernetes-session

./bin/kubernetes-session.sh
