Node.js 编写动态创建的 YAML 为生态系统创建 Docker compose 文件(使用 jsyaml)

Question: Has anyone been able to work with the js-yaml library to write a docker compose like this?个

上下文:

我正在处理DotNet模板，并为我们的团队提供了一些预定义的应用程序架构模式.我想更进一步，为整个生态系统创建docker compose个.

主要问题是我需要更改令牌并写入YAML.

我已经在模板中try 了以下两种方法，无法获得有效的YAML输出.

command: "./daprd -app-id ecosystemtemplate-${application} -app-port ${EXPOSED_PORT:-4443} --resources-path /app/config"

command: [ "./daprd", "-app-id", "ecosystemtemplate-${application}", "-app-port", "${EXPOSED_PORT:-4443}", "--resources-path", "/app/config"

我如何让js-yaml库尊重被引用的项目，并应该保留引用？

取以上command个YAML并通过json2yaml.com运行，YAML-&>JSON和JSON-&>YAML看起来都是正确的.为了重新创建它，我首先将模板YAML复制到UI中，然后复制json并再次粘贴，从而更新YAML输出，这看起来是正确的.

如果我使用NodeJS运行它，我在YAML中会得到不正确的输出.image、command和network_mode都需要引号.我已经用了太多的方式来列出这一点.

当PoC转移到产品就绪的企业级应用程序时，PoC将变得更加参与.

示例:

根据模板，我创建了一个Solution.json文件，其中包含生态系统模板使用的信息.

以下代码用于读取Solution.json

async function createDockerComposeYaml () {
    console.log("Creating Docker Compose");
    const fileName = 'docker-compose.yml';
    const applicationDescriptor = '${application}';

    await (async () => {
        try {
          await fs.unlink(fileName);
        } catch (e) {
          // Swallow the error.
          // Normally happens when the file does not exist the first time.
        }
      })();

    try {
        const dockerComposeYaml = await fs.readFile('./docker-templates/compose/Docker-compose-template.yml', 'utf-8');
        const serviceYamlTokenized = await fs.readFile('./docker-templates/compose/Docker-compose-service-template.yml', 'utf-8');
        const daprSidecarYamlTokenized = await fs.readFile('./docker-templates/compose/Docker-compose-service-dapr-sidecar-template.yml', 'utf-8');

        let dockerCompose = YAML.load(dockerComposeYaml);

        solutions.forEach(solution => {
            // Build the service for the application.
            let serviceYaml = serviceYamlTokenized.replaceAll('${application}', solution.name.toLowerCase());
            serviceYaml = serviceYaml.replace('${dockerfile}', solution.dockerfile);
            const service = YAML.load(serviceYaml);

            // Build the service for the application dapr sidecar.
            const serviceSidecarYaml = daprSidecarYamlTokenized.replaceAll('${application}', solution.name.toLowerCase());
            const serviceSidecar = YAML.load(serviceSidecarYaml);

            if (dockerCompose.services === null) {
                dockerCompose.services = [];
            }

            dockerCompose.services.push(service);
            dockerCompose.services.push(serviceSidecar);
        });

        writeFile(fileName, YAML.dump(dockerCompose, { 'forceQuotes': true }));
    } catch(e) {
        console.log(e);
    }
}
