The `bind() to 0.0.0.0:443 failed (13: Permission denied)` error occurs
because port 443 is a privileged port (< 1024) that requires root or the
`NET_BIND_SERVICE` capability. The chart runs APISIX as non-root by default.
**Solutions:**
1. **Use a high port** (recommended): Set `apisix.ssl.containerPort: 9443`
(values.yaml line 310, this is the default)
2. **Add capability**: Configure `securityContext` (values.yaml lines 47-53):
```yaml
securityContext:
capabilities:
add:
- NET_BIND_SERVICE
```
The default SSL container port is already 9443, so this issue typically
arises from custom overrides.
Closing as this is a usage question about Linux port binding. If you still
have questions, please feel free to reopen.
