How can spring boot application instances be packaged in testcontainers-CodePudding

there are several instances of applications that interact with each other (microservices)
There are docker images of these spring boot apps
Is it possible to use these docker images in test container to deploy in tests and how is it possible to do this

There is no need to take into account the time to work and initialization of such tests, this is not the main thing in this situation.

CodePudding user response：

Testcontainers offers GenericContainer which allow you to use images in the registry. For example, let's say you have a image for your service called myorganization/greetings-service:2.0.0 which listen request in the port 8080. Then you can use:

GenericContainer container = new GenericContainer("myorganization/greetings-service:2.0.0")
           .withExposedPort(8080)
           .waitingFor(Wait.forHttp("/"));

and later you can get the host and port using container.getHost() and container.getMappedPort(8080).

Hope this can help you
