本文记录使用Dockerfile Maven Plugin 将Docker镜像Push到AWS ECR (Elastic Container Registry),碰到了一些问题,并进行了解决。
问题解决
AWS ECR (Elastic Container Registry)的登录
使用以下AWS指令来登录AWS ECR:
[ec2-user@ip-10-0-3-241 ~]$ export AWS_ACCESS_KEY_ID="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx..."
[ec2-user@ip-10-0-3-241 ~]$
[ec2-user@ip-10-0-3-241 ~]$ export AWS_SECRET_ACCESS_KEY="yyyyyyyyyyyyyyyyyyyyyyyyyyy..."
[ec2-user@ip-10-0-3-241 ~]$
[ec2-user@ip-10-0-3-241 ~]$ export AWS_SESSION_TOKEN="zzzzzzzzzzzzzzzzzzzzzz..."[ec2-user@ip-10-0-3-241 ~]$ aws ecr get-login-password --region ap-southeast-1 | docker login --username AWS --password-stdin 123456789012.dkr.ecr.ap-southeast-1.amazonaws.com
登录后密钥会存放主在这里~/.docker/config.json
:
[ec2-user@ip-10-0-3-241 ~]$ cat ~/.docker/config.json
{"auths": {"123456789012.dkr.ecr.ap-southeast-1.amazonaws.com": {"auth": "jjjjjjjjjjjjjjjjjjjjjjjjjjjjj..."}}
}
如果使用credHelpers
,那么~/.docker/config.json
就会更新为以下:
{"credHelpers": {"<ecr-id>.dkr.ecr.<aws-region>.amazonaws.com": "ecr-login"},//...
}
问题 pull access denied for jdk, repository does not exist
问题:
DOCKER error: Pull access denied for frolvlad/alpine-oraclejdk8, repository does not exist or may require 'docker login'
可能由于仓库不存在了,这里显示jdk
找不到了。
进行以下修改,原本的Dockerfile
内容:
FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD spring-petclinic-rest-1.7.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
修改为 openjdk
,如以下,问题解决。
FROM openjdk:8
VOLUME /tmp
ADD target/spring-petclinic-rest-1.7.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]
问题 Could not acquire image ID or digest following build
Could not acquire image ID or digest following build
的问题可能由以下几个原因导致:
- dockerfile-maven-plugin版本较低,需要从1.3.×升级到1.4.×即可,这已经使用了1.4.13,所以应该不是这个原因导致的。
- 需要将
Dockerfile
放到与`pom.xml``的根目录,进行了尝试,然而并没有解决问题。 - 那么最后主不剩下最后一个可能,
Dockerfile
配置错误,需要进行排查。
排查Dockerfile
配置错误比较麻烦,需要使用docker指令进行测试。
[ec2-user@ip-10-0-3-241 ~]$ docker build --file Dockerfile --tag 123456789012.dkr.ecr.ap-southeast-1.amazonaws.com/spring-petclinic-rest:1.7 .Sending build context to Docker daemon 36.96MB

ADD failed: file not found in build context or excluded by .dockerignore: stat spring-petclinic-rest-1.7.jar: file does not exist
以上Dockerfile
配置路配置有些问题,进行修改,解决问题。
使用以下指令进行Push测试:
[ec2-user@ip-10-0-3-241 ~]$ docker tag 123456789012.dkr.ecr.ap-southeast-1.amazonaws.com/spring-petclinic-rest:1.7 123456789012.dkr.ecr.ap-southeast-1.amazonaws.com/spring-petclinic-rest:latest
[ec2-user@ip-10-0-3-241 ~]$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

[ec2-user@ip-10-0-3-241 ~]$ docker push 123456789012.dkr.ecr.ap-southeast-1.amazonaws.com/spring-petclinic-rest:latest
The push refers to repository [123456789012.dkr.ecr.ap-southeast-1.amazonaws.com/spring-petclinic-rest]

dockerfile-maven-plugin 使用
pom.xml记录如下:
<properties><!-- Generic properties --><java.version>1.8</java.version><docker.registry.host>${env.docker_registry_host}</docker.registry.host><docker.image.prefix>123456789012.dkr.ecr.ap-southeast-1.amazonaws.com</docker.image.prefix><docker.image.name>${project.artifactId}</docker.image.name><docker.image.tag>${project.version}</docker.image.tag><docker.file>Dockerfile</docker.file></properties>

运行maven指令可以成功编译并将image推送到AWS云:
mvn clean package dockerfile:build -DpushImage -Dmaven.test.skip=true
