Docker Compose: Updating Image for adrs-ui Service

This Docker Compose file defines a multi-container application with two services: 'adrs-ui' and 'adrs-ui_test'. Both services use the same image: '192.168.2.78:5000/dev/ly-mssp-auth-uiaaaa:2.2'.

The goal is to update the image value for the 'adrs-ui' service to 'TEST'.

You can use a Java library like SnakeYAML to parse and update the YAML file. Here's a code snippet demonstrating this:

import org.yaml.snakeyaml.DumperOptions;
import org.yaml.snakeyaml.Yaml;
import org.yaml.snakeyaml.nodes.Node;
import org.yaml.snakeyaml.nodes.ScalarNode;
import org.yaml.snakeyaml.nodes.Tag;
import org.yaml.snakeyaml.representer.Representer;
import org.yaml.snakeyaml.resolver.Resolver;

import java.io.*;
import java.util.LinkedHashMap;
import java.util.Map;

public class UpdateYaml {
    public static void main(String[] args) throws IOException {
        String filename = "your-yaml-file.yaml";
        String hostnameToUpdate = "adrs-ui";
        String newImageValue = "TEST";

        // 读取YAML文件
        InputStream inputStream = new FileInputStream(new File(filename));
        Yaml yaml = new Yaml();
        Map<String, Object> data = yaml.load(inputStream);

        // 更新hostname为adrs-ui的image值
        updateImageValue(data, hostnameToUpdate, newImageValue);

        // 将更新后的数据写入到新的YAML文件中
        DumperOptions options = new DumperOptions();
        options.setDefaultFlowStyle(DumperOptions.FlowStyle.BLOCK);
        Yaml updatedYaml = new Yaml(new Representer(), options);
        FileWriter writer = new FileWriter(new File("updated-yaml-file.yaml"));
        updatedYaml.dump(data, writer);
        writer.close();
    }

    private static void updateImageValue(Map<String, Object> data, String hostname, String newImageValue) {
        if (data.containsKey("services")) {
            Map<String, Object> services = (Map<String, Object>) data.get("services");
            for (Map.Entry<String, Object> entry : services.entrySet()) {
                Map<String, Object> service = (Map<String, Object>) entry.getValue();
                if (service.containsKey("image") && service.containsKey("depends_on")) {
                    String serviceName = entry.getKey();
                    Map<String, Object> dependsOn = (Map<String, Object>) service.get("depends_on");
                    if (dependsOn.containsKey(hostname)) {
                        service.put("image", newImageValue);
                        dependsOn.put(hostname, newImageValue);
                    }
                }
            }
        }
    }
}

Remember to replace "your-yaml-file.yaml" with the actual path to your Docker Compose file. This code will create a new file called "updated-yaml-file.yaml" with the updated image value for the 'adrs-ui' service.
