The short version

  • Only Docker has a free tier, so it costs nothing to try first.
  • Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; Rootly pricing higher than some competitors for basic features
  • They diverge on capability: Docker covers Container runtime, Rootly covers AI SRE automation.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docker

  • Shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation
  • Daemon socket exposure grants full root access to the host if compromised
  • Requires careful secrets management - credentials embedded in images or environment variables are easily harvested by attackers
  • Resource management complexity - misbehaving or compromised containers can consume all resources causing denial of service
  • Orchestration complexity - Docker Swarm is less capable than Kubernetes, requiring external tools for production deployments

Rootly

  • Pricing higher than some competitors for basic features
  • AI SRE features require separate contact-sales engagement
  • Learning curve for advanced automation features
  • Per-user pricing increases costs as team grows

Answered from the vendors’ own pages

Docker: What is Docker pricing?

Docker offers a freemium model with Docker Personal free, Docker Pro at $11/user/month, Docker Team at $16/user/month, and Docker Business at $24/user/month. Each tier includes Docker Desktop, Docker Hub, and Docker Scout with different usage limits.

Source
Rootly: How much does Rootly cost?

Rootly charges $20/user/month for both Incident Response and On-Call Essentials plans. Enterprise plans require contacting sales. Startups under 100 employees with less than $50M raised get up to 50% discount.

Source
Docker: Can I use Docker in production?

Yes. Docker is used extensively in production environments. However, for container orchestration at scale, Kubernetes is typically paired with Docker to automate deployment, scaling, and management across clusters.

Source
Rootly: What is Rootly AI SRE?

AI SRE is an advanced feature that provides automated root cause analysis, alert correlation with system changes, impact analysis, and remediation suggestions. Pricing requires contact with sales.

Source
Docker: What are the main security concerns with Docker?

Key security risks include container breakout vulnerabilities through shared kernel exploits, daemon socket exposure that grants root access if compromised, weak isolation between containers, and credential leakage if secrets are embedded in images.

Source
Rootly: Does Rootly integrate with Slack?

Yes, Rootly natively integrates with Slack for incident response workflows, allowing teams to manage incidents directly in Slack.

Source
Docker: Does Docker integrate with CI/CD systems?

Yes. Docker integrates with Jenkins, GitHub, and other CI/CD systems. The typical workflow involves GitHub repositories triggering automated builds in Jenkins, which prepare Dockerfiles and push images to Docker Hub for deployment.

Source
Rootly: Are there discounts for small companies?

Yes, startups under 100 employees or less than 25 employees can get special pricing up to 50% discount. Contact Rootly sales for details.
