Kadir za ka tiyata Docker containers?

Question

Accepted Answer

Tiyatawa Docker ya aiki da matakari masu yawa — **hotuna masu karamin girma da amsanmu**, **gudu ba da root**, **duba cututtuka**, **jiyewa sirri**, **iyakoki jimlandi da karfin aiki**, da **tiyatawa gida/daemon**. Tsaron container ya kasance mahimmanci saboda takunkunta na iya kamatawa da container da gida.

## Tsaron hoto

```text
✓ Use MINIMAL base images (alpine, distroless) → fewer packages = smaller attack surface
✓ Use TRUSTED/official images; pin specific versions/DIGESTS (not "latest")
✓ SCAN images for vulnerabilities (Trivy, docker scout, Snyk) — in CI and regularly
✓ Keep base images UPDATED (patch known CVEs)
✓ Don't include secrets or unnecessary tools in images
```

## Tsaron aiki

```text
✓ Run as NON-ROOT (USER instruction) — a root container that's compromised is far more
  dangerous (especially with host access). This is one of the most important practices.
✓ Drop capabilities (--cap-drop ALL, add only needed ones) — limit what the container can do
✓ Read-only filesystem (--read-only) where possible
✓ no-new-privileges (prevent privilege escalation)
✓ Set RESOURCE LIMITS (prevent DoS from resource exhaustion)
✓ NEVER run --privileged unless absolutely necessary (it gives near-host access)
```

## Sirri da tsaron gida

```text
✓ Don't bake secrets into images; use secrets management at runtime
✓ Protect the DOCKER DAEMON — the daemon runs as root; access to it = root on the host
  (don't expose the Docker socket; mounting /var/run/docker.sock into a container is risky)
✓ Keep the host and Docker engine PATCHED; use minimal/hardened host OS
✓ Isolate networks; limit container-to-container and container-to-host access
✓ Consider rootless Docker / user namespaces for stronger isolation
```
