🧹 Outside diff range and nitpick comments (6)
Server/package.json (1)
20-20: Yo dawg, we need some Docker setup docs!Since dockerode requires specific permissions to access the Docker daemon (usually through Unix socket), we should ensure there's proper documentation for production deployment.
Consider adding:
- Required Docker permissions
- Unix socket configuration
- Security best practices for Docker daemon access
Would you like me to help create a Docker setup guide for the documentation?
Server/db/models/Monitor.js (1)
31-31: Mom's spaghetti suggestion: Consider enhancing the schema for Docker-specific needs! 🐳The current schema might benefit from additional Docker-specific fields to support comprehensive container monitoring:
Consider adding these Docker-specific fields:
type: { type: String, required: true, enum: ["http", "ping", "pagespeed", "hardware", "docker"], }, url: { type: String, required: true, }, +dockerConfig: { + type: { + containerName: { type: String }, + healthCheckEndpoint: { type: String }, + resourceLimits: { + cpuLimit: { type: Number }, + memoryLimit: { type: String }, + }, + }, + required: function() { return this.type === 'docker' }, + _id: false, +}, thresholds: { type: { usage_cpu: { type: Number }, usage_memory: { type: Number }, usage_disk: { type: Number }, + container_restarts: { type: Number }, }, _id: false, },This would provide better structure for Docker-specific monitoring configuration and thresholds.
Also applies to: 33-35, 46-54
Server/utils/messages.js (1)
129-131: Mom's spaghetti approves this success message! 🍝The Docker success message is well-crafted and consistently placed with other operation-specific success messages. However, consider adding more specific success messages for different Docker operations.
Consider adding these additional Docker success messages for better granularity:
// Docker DOCKER_SUCCESS: "Docker container status fetched successfully", +DOCKER_CONNECT_SUCCESS: "Successfully connected to Docker daemon", +DOCKER_CONTAINER_RUNNING: "Docker container is running", +DOCKER_CONTAINER_STOPPED: "Docker container is stopped",Server/service/statusService.js (2)
136-136: Yo dawg, the basic integration looks solid but we could level up the docker monitoring game! 🎤The mapping of docker type to
createCheckis clean and follows the same pattern as HTTP/ping monitors. This aligns well with the current focus on container running status.However, similar to how we handle hardware and pagespeed checks with additional metrics, we could enhance the docker monitoring by capturing container-specific stats.
Consider extending the
buildCheckmethod to include docker metrics like:buildCheck = (networkResponse) => { // ... existing code ... + if (type === "docker") { + const { state, status, memory, cpu } = payload?.data ?? {}; + check.containerState = state; + check.containerStatus = status; + check.containerStats = { + memory, + cpu + }; + } return check; };
136-136: Mom's spaghetti suggestion: Add documentation for the docker type! 📝The
insertCheckmethod's JSDoc comments should be updated to include the docker type in the networkResponse.type description.* @param {Object} networkResponse - The network response object. * @param {string} networkResponse.monitorId - The monitor ID. - * @param {string} networkResponse.type - The type of the response. + * @param {string} networkResponse.type - The type of the response (http, ping, pagespeed, hardware, docker).Server/service/jobQueue.js (1)
183-184: Yo dawg, these error handling changes are tight but we could make them even better!The use of the nullish coalescing operator (??) for error attribution is clean and consistent. However, we could enhance the error handling to capture more context about Docker-related failures.
Consider adding Docker-specific error context:
- service: error.service ?? SERVICE_NAME, - method: error.method ?? "createJobHandler", + service: error.service ?? SERVICE_NAME, + method: error.method ?? "createJobHandler", + context: { + isDockerMonitor: job.data?.type === 'docker', + containerId: job.data?.url, // Docker image ID is stored in url + errorType: error.code ?? 'unknown' + }This would help diagnose Docker-specific issues more effectively as we roll out the new monitor type.

Server/package.json (1)
20-20: Yo, the dockerode dependency looks solid, but let's check those security implications!
The addition of dockerode 4.0.2 is appropriate for implementing Docker monitoring functionality. However, since it requires access to the Docker daemon, we should verify the security setup.
Server/db/models/Monitor.js (1)
31-31: Yo dawg, the enum addition looks good! 🎯
The addition of "docker" type aligns with the PR objectives for Docker monitoring support.

Server/utils/messages.js (1)
58-60: Yo dawg, this error message is straight fire! 🔥
The Docker error message is clear, concise, and follows the existing error message patterns. It's properly placed in the operation-specific errors section.
Server/index.js (2)
134-134: Mom's spaghetti moment - we need error handling! 🍝
While passing Docker to NetworkService is correct, we should ensure proper error handling for Docker daemon connection failures.
#!/bin/bash
# Description: Check for error handling in NetworkService
# Look for try-catch blocks around Docker operations
rg -A 5 "try.*{.*Docker"
# Check if NetworkService has error handling for Docker
ast-grep --pattern 'class NetworkService {
$$$
catch($_) {
$$$
Docker
$$$
}
$$$
}'Consider implementing a fallback mechanism when Docker daemon is unavailable:
- Log the error but don't crash the service
- Mark Docker-based monitors as "unknown" status
- Retry connection to Docker daemon periodically
31-31: Yo dawg, this Docker import looks legit! 🍝
The dockerode import is properly placed with other service dependencies. Let's make sure we've got our dependencies straight though.
Server/service/jobQueue.js (1)
Line range hint 1-424: Yo, we need to prep this queue for the Docker heat! 🔥
While the current implementation will handle Docker monitors like any other type, we should consider adding Docker-specific enhancements:
- Job Retry Strategy: Docker operations might need different retry intervals compared to HTTP/ping monitors
- Resource Management: Docker operations could be more resource-intensive
- Error Classification: We should categorize Docker-specific errors (daemon connection issues, image pull failures, etc.)
Consider implementing a monitor-type-specific configuration:
const MONITOR_TYPE_CONFIG = {
docker: {
retryDelay: 30000, // longer retry for Docker ops
maxAttempts: 3, // limit retries for resource management
jobsPerWorker: 3 // fewer Docker jobs per worker
},
http: {
retryDelay: 5000,
maxAttempts: 5,
jobsPerWorker: 5
}
};Let's check if there are any existing Docker-specific configurations:

🛠️ Refactor suggestion
Security concern: Direct access to Docker socket.
Accessing /var/run/docker.sock directly can pose significant security risks, as it may grant root-level access to the Docker daemon. Consider making the socket path configurable or adding authentication measures to mitigate potential vulnerabilities.

- const docker = new this.Docker({ socketPath: "/var/run/docker.sock" });
+ const docker = new this.Docker({ socketPath: process.env.DOCKER_SOCKET_PATH || "/var/run/docker.sock" });Ensure to set DOCKER_SOCKET_PATH in your environment variables when deploying.

222-227: Avoid redefining 'Docker' within individual tests; stub methods instead.Redefining the 'Docker' class inside test cases can make the tests harder to maintain and understand. Instead, consider stubbing the
getContainermethod directly on the existing 'Docker' instance. This approach keeps the tests cleaner and focuses on the behaviour being tested.Example:
sinon.stub(networkService.Docker.prototype, 'getContainer').returns({ inspect: sinon.stub().resolves({ State: { Status: "stopped" } }), });

232-237: Clean error handling right there!
The error handling implementation is on point with proper context and message formatting.
Line range hint 249-262: Let's make sure all monitor types are handled properly
The switch statement looks good, but let's verify we haven't missed any monitor types.
✅ Verification successful
All monitor types are properly handled in the getStatus method. Nothing to stress about!

6-6: Initialized 'Docker' alongside other dependencies.
Including 'Docker' with 'axios', 'ping', and 'logger' sets up the necessary environment for Docker-related tests. This integration is essential for testing the new Docker monitor functionality.
15-19: Mocked the 'Docker' class effectively for testing.
Creating a mock 'Docker' class with a stubbed getContainer method that returns a resolved promise emulates Docker interactions accurately. This approach allows for controlled and reliable testing of Docker-related methods.
28-28: Passed 'Docker' to 'NetworkService' constructor.
Updating the NetworkService instantiation to include 'Docker' ensures that Docker functionalities are accessible within the service. This change aligns with the requirements for supporting Docker monitors.
211-259: Added comprehensive tests for 'requestDocker' method.
The new test suite for requestDocker covers various scenarios:
- Successful retrieval of Docker container status.
- Handling of non-running containers.
- Error handling during container inspection.
- Exception throwing when operations fail.
These tests enhance the reliability and robustness of the Docker monitoring implementation.
267-267: Stubbed 'requestDocker' method in 'getStatus' tests.
Adding requestDocker to the stubs ensures that when getStatus is tested, it doesn't execute the actual implementation. This allows for testing the control flow without side effects, which is good practice in unit testing.
273-346: Expanded 'getStatus' tests to handle 'docker' type.
Including test cases for the 'docker' monitor type ensures that getStatus correctly delegates to requestDocker. Additionally, the tests for unknown or undefined types enhance error handling verification. Together, these tests improve the robustness of the NetworkService.

🛠️ Refactor suggestion
Include 'afterEach' to restore stubs and mocks between tests.
In the requestDocker test suite, stubs and mocks are configured but not restored after each test. This could lead to test interference and unreliable results. To maintain isolation and ensure each test runs independently, consider adding an afterEach block to restore the stubs:
+ afterEach(() => {
+ sinon.restore();
+ });Committable suggestion skipped: line range outside the PR's diff.

Take'r up a notch with additional test cases, buddy!
The Docker test suite looks solid but could use a couple more test cases to handle these scenarios:
it("should handle malformed container state", async () => {
Docker = class {
listContainers = sinon.stub().resolves([{ Id: "abc123" }]);
getContainer = sinon.stub().returns({
inspect: sinon.stub().resolves({ State: {} }) // Missing Status
});
};
networkService = new NetworkService(axios, ping, logger, http, Docker);
const job = { data: { url: "abc123", _id: "123", type: "docker" } };
const dockerResult = await networkService.requestDocker(job);
expect(dockerResult.status).to.be.false;
expect(dockerResult.code).to.equal(networkService.NETWORK_ERROR);
});
it("should handle Docker daemon connection errors", async () => {
Docker = class {
listContainers = sinon.stub().rejects(new Error("Cannot connect to the Docker daemon"));
};
networkService = new NetworkService(axios, ping, logger, http, Docker);
const job = { data: { url: "abc123", _id: "123", type: "docker" } };
try {
await networkService.requestDocker(job);
} catch (error) {
expect(error.message).to.equal("Cannot connect to the Docker daemon");
}
});
This PR adds support for a docker monitor. This is a subtype of uptime monitor.
-[x] Update JobQueue, NetworkSerivce, and StatusService to support docker type monitors
Currently there is no need for a distinct docker type check as we are currently only interested in whether or not the container is running. This is the same information that we have for a base http/ping type
Check, so that type is used. We can implement a distinct docker type check if we need more information later.Docker monitors use a docker image ID in the
urlfield of the monitor.
