如何从 AWS ECR 中提取私有 docker 图像以与 Java 中的 Testcontainers 库一起使用

Question

I am trying to programmatically create and spin up a MongoDBContainer from a docker image hosted in a private AWS ECR repository. This will be used for automated integration tests, will be run locally and within CICD pipelines. But that doesn't work (see 2.). When I pull the image from DockerHub (see 1.) it works. Code I have so far is:

@Testcontainers
@AutoConfigureDataMongo
public interface MongoTestContainer {

  // 1. This pull the image directly from DockerHub, and it works.
  //@Container MongoDBContainer mongoDBContainer = new
  //MongoDBContainer("mongo:5.0.11");

  // 2. This should pull the image from AWS ECR but doesn't work.
  @Container MongoDBContainer mongoDBContainer = new
  MongoDBContainer("<account>.dkr.ecr.<region>.amazonaws.com/<imageName>:<version>");

  
  @DynamicPropertySource
  static void setProperties(DynamicPropertyRegistry registry) {
    registry.add("spring.data.mongodb.uri", mongoDBContainer::getReplicaSetUrl);
  }
}

Any ideas?

Kind regards, John

Using the 2nd approach should fail throwing an exception and the message should provide the fix which I would mention below. There are two options:

1. In ~/.testcontainers.properties add hub.image.name.prefix=custom.dockerhub.repository/
2. Use new MongoDBContainer(DockerImageName.parse("<account>.dkr.ecr.<region>.amazonaws.com/<imageName>:<version>").asCompatibleSubstituteFor("mongo")
