Understanding Argo CD
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It automates the deployment of the desired application states in the specified target environments. Argo CD monitors applications and compares the live state against the desired state, allowing for automated synchronization and rollback capabilities.
Identifying the Symptom
One common issue that users may encounter is the Argo CD server running out of disk space. This can manifest as errors in the Argo CD UI, failed deployments, or an inability to perform operations that require disk space.
Observed Errors
When the server disk space is full, you might observe errors such as:
- "No space left on device"
- Failed application syncs
- Inability to write logs or cache data
Root Cause Analysis
The primary cause of this issue is the exhaustion of available disk space on the server hosting Argo CD. This can occur due to excessive log files, large application manifests, or insufficient initial disk allocation.
Impact on Operations
When disk space is full, Argo CD cannot perform essential operations such as logging, syncing applications, or storing necessary data. This can lead to degraded performance or complete service outages.
Steps to Resolve the Issue
To resolve the issue of full disk space on the Argo CD server, follow these steps:
1. Free Up Disk Space
Start by identifying and removing unnecessary files. You can use the following commands to find large files and directories:
du -ah / | sort -n -r | head -n 20
Remove unnecessary log files or temporary files:
rm -rf /var/log/argo-cd/*.log
2. Increase Disk Capacity
If cleaning up files is not sufficient, consider increasing the disk capacity. This can be done by resizing the disk in your cloud provider's console or adding additional storage volumes.
3. Configure Log Rotation
Implement log rotation to prevent logs from consuming excessive disk space. You can configure logrotate on Linux systems:
/etc/logrotate.d/argo-cd {
daily
missingok
rotate 7
compress
delaycompress
notifempty
create 0640 root root
}
