In Java code I need to manage docker containers (restart, stop, start ...) using Docker-java library. https://github.com/docker-java/docker-java
In Docker-Java examples I found the way to create and get container: https://github.com/docker-java/docker-java/wiki
DockerClient dockerClient = DockerClientBuilder.getInstance().build();
CreateContainerResponse container = dockerClient.createContainerCmd("nginx")
.exec();
System.out.println(container.getId());
dockerClient.restartContainerCmd(container.getId());
in command line we can use:
docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4dd858fe9022 nginx "nginx -g 'daemon of…" 42 hours ago Up 42 hours 0.0.0.0:80->80/tcp webserver
But I need to do it by JAVA code. I need to get the IDs for existing containers then get their Ip addresses and use restartContainerCmd method to restart it.
Found solution. Put it here in case if someone has same question:
Build a simple DockerClient then create ListContainersCmd object and use exec() method, then iterate through list of containers and find the container associates with IP and then get container Id; with Id we can restart container:
DockerClient dockerClient = DockerClientBuilder.getInstance().build();
ListContainersCmd listContainersCmd = dockerClient.listContainersCmd().withShowAll(true);
for (Container container: listContainersCmd.exec()) {
if (container.toString().contains("192.168.1.105")){
dockerClient.restartContainerCmd(container.getId()).exec();
}
}
You may be looking for a utility method like this:
void restartContainers(DockerClient dockerClient) {
dockerClient.listContainersCmd().exec().stream()
.map(Container::getId)
.map(dockerClient::restartContainerCmd)
.forEach(RestartContainerCmd::exec);
}
