Load Analysis and Common User Issues
Coolify: Load and Common Issues
Resource Load:
Requirements: Depend on what you plan to run with Coolify. A basic installation requires at least 2 GB of RAM, but running multiple apps and databases will require more resources.
Performance issues: Users report high CPU and RAM usage, especially during builds. This can slow down the control panel and even crash the server. It’s recommended to use a swap file to virtually increase RAM.
Common User Issues:
Proxy issues: The most common problem. Applications may randomly stop working until the proxy is restarted. The control panel may also become unavailable due to incorrect proxy configuration.
High resource consumption: Coolify can use a lot of memory and disk space, making users look for lighter alternatives.
Build issues: Builds can be slow or crash the server, especially on VPS with limited resources.
Slow control panel: The control panel may load slowly, or some pages may not load at all.
SSL issues: Certificate errors with Cloudflare (error 526).
Slow server response time: Slow initial web server loading.
Dokploy: Load and Common Issues
Resource Load:
Monitoring: Dokploy provides real-time monitoring of CPU, memory, disk, and network traffic. Lower refresh intervals mean more accurate data but also higher resource consumption.
Comparison with Coolify: Dokploy is noted to consume significantly fewer resources compared to Coolify.
High CPU usage: In some cases, high CPU usage (around 20%) is observed after enabling HTTPS.
Server crashes: When deploying resource-intensive applications (close to 100% CPU and memory usage), the server may crash.
Common User Issues:
Inaccurate monitoring data: The project monitoring page may show incorrect resource usage since it displays the resources allocated to the app rather than the entire server.
Frequent 504 errors and low uptime: Services may crash and restart throughout the day, resulting in low uptime (down to 30%).
Response delays: Significant response delays (from 300 ms to 1.4 seconds) for APIs deployed with Dokploy.
Deployment issues: Deployments may get stuck in the "Running" state indefinitely.
Docker Registry authentication issues: Authentication errors if credentials or token permissions are incorrect.
Image not found: Errors occur if the image name or tag is written incorrectly.
Slow HTTPS: Significant slowdown when using HTTPS.
Configuration issues: Incorrect container, port, or volume settings can lead to problems.
Bad Gateway: Problems with Bad Gateway errors.
CapRover: Load and Common Issues
Resource Load:
Monitoring: CapRover provides resource monitoring, allowing you to track memory and CPU usage.
Scaling: CapRover offers several scaling options, allowing apps to run in multiple processes to utilize all server resources.
Resource limits: You can set resource limits for a specific service. For example, you can cap it at 2 CPUs and 100 MB RAM.
High resource consumption: Users report high resource usage even for almost empty WordPress sites with MySQL and MariaDB.
Common User Issues:
HTTPS issues: Failures when enabling HTTPS for multiple apps with error "1107: Unexpected output".
Deployment issues: Periodic port crashes on containers after VM reboot, leading to 502 errors.
Mysterious crashes: Users report unexplained failures where the control panel stops loading with the message "Something bad happened".
Connection issues: Inability to connect to
<server_ip>:3000.Storage issues: Persistent storage issues, with a recommendation to use cloud storage like S3 or GCS.
Missing files: Problems with missing files when deploying certain apps (e.g., with Trame).
Conflict with Nginx Proxy Manager: Nginx Proxy Manager conflicts with CapRover as both try to manage domains and proxies.
Dokku: Load and Common Issues
Resource Load:
Resource management: By default, Dokku provides unrestricted access to resources for deployed apps. You can limit resource usage per app or process.
Monitoring: Dokku does not manage monitoring and alerts for resource usage directly, but external tools can be used for server monitoring.
RAM requirements: App builds may consume significant RAM, which can be an issue for VPS with limited resources (e.g., 512 MB RAM).
High CPU usage: Users report CPU spikes that trigger alerts.
Common User Issues:
Deployment issues:
"Not a git repository"
"Unable to select a buildpack"
"Pull access denied"
"Failed to load ..."
Apps may get stuck in the "Running" state or fail to start after a Dokku update.
SSL issues: Apps configured to enforce secure connections/HSTS may not work if SSL is not set up.
Performance issues: Users report performance problems on VPS, including high CPU usage.
Storage issues: Problems with persistent storage, although Dokku provides a plugin for storage management.
Zero-downtime issues: Disabling zero-downtime deployment can resolve some problems related to app restarts.
Updates: Known bugs during updates from older Dokku versions can lead to app launch issues.
