update_apprun

Instructions

Implementation Reference

• src/server.ts:2387-2437 (handler)

  Handler function that executes the 'update_apprun' tool: fetches current app data, merges with provided updates (name, description, dockerImage, planId, environment), sends PUT request to AppRun API, returns result.

  } else if (request.params.name === 'update_apprun') {
    try {
      validateCredentials();
      
      const appId = request.params.arguments?.appId as string;
      if (!appId) {
        throw new Error('AppRun application ID is required');
      }
      
      // Get current application data first
      const currentApp = await fetchFromAppRunAPI(`/applications/${appId}`);
      
      // Extract current values
      const currentName = currentApp.name || '';
      const currentDescription = currentApp.description || '';
      const currentPlanId = currentApp.planId || '';
      const currentDockerImage = currentApp.image || '';
      const currentEnvironment = currentApp.environment || [];
      
      // Get update values from request or use current values
      const name = request.params.arguments?.name as string || currentName;
      const description = request.params.arguments?.description as string || currentDescription;
      const planId = request.params.arguments?.planId as string || currentPlanId;
      const dockerImage = request.params.arguments?.dockerImage as string || currentDockerImage;
      const environment = request.params.arguments?.environment as Array<{key: string, value: string}> || 
        currentEnvironment.map((env: {Key: string, Value: string}) => ({ key: env.Key, value: env.Value }));
      
      const zone = request.params.arguments?.zone as string || DEFAULT_ZONE;
      
      const updateBody = {
        name: name,
        description: description,
        planId: planId,
        image: dockerImage,
        environment: environment.map(env => ({ key: env.key, value: env.value })),
      };
      
      const updateResult = await fetchFromAppRunAPI(`/applications/${appId}`, 'PUT', updateBody);
      
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(updateResult, null, 2)
          }
        ]
      };
    } catch (error) {
      console.error('Error calling tool:', error);
      throw error;
    }

• src/server.ts:75-122 (helper)

  Helper function used by update_apprun (and other AppRun tools) to make authenticated HTTPS requests to Sakura Cloud AppRun API.

  async function fetchFromAppRunAPI(path: string, method: string = 'GET', bodyData?: any): Promise<any> {
    return new Promise((resolve, reject) => {
      validateCredentials();
      
      const options = {
        hostname: 'secure.sakura.ad.jp',
        port: 443,
        path: `/cloud/api/apprun/1.0/apprun/api${path}`,
        method: method,
        headers: {
          'Accept': 'application/json',
          'Content-Type': 'application/json',
          'Authorization': `Basic ${Buffer.from(`${SACLOUD_API_TOKEN}:${SACLOUD_API_SECRET}`).toString('base64')}`
        }
      };
  
      const req = https.request(options, (res) => {
        let data = '';
        
        res.on('data', (chunk) => {
          data += chunk;
        });
        
        res.on('end', () => {
          try {
            if (data) {
              const parsedData = JSON.parse(data);
              resolve(parsedData);
            } else {
              resolve({});
            }
          } catch (err) {
            reject(new Error(`Failed to parse response: ${err}`));
          }
        });
      });
      
      req.on('error', (error) => {
        reject(error);
      });
      
      if (bodyData && (method === 'POST' || method === 'PUT')) {
        req.write(JSON.stringify(bodyData));
      }
      
      req.end();
    });
  }
