The short version

  • Each has a real cost: Docker shared kernel creates security vulnerabilities when containers share the same OS kernel that can bypass container isolation; Infisical free tier limited to 5 identities, suitable only for small teams or evaluation
  • They diverge on capability: Docker covers Container runtime, Infisical covers Certificate management.

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

Infisical

  • Free tier limited to 5 identities, suitable only for small teams or evaluation
  • Pricing tiers are per-identity, which scales costs with team size
  • Certificate management requires Enterprise plan for advanced features like wildcards
  • Privileged access tier is separate billing from secrets management

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
Infisical: How is pricing calculated for Secrets Management?

Pricing is per-identity per month. Free tier includes 5 identities. Pro tier is $20/identity/month, Advanced is $40/identity/month. All pricing in USD.

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
Infisical: Can I self-host Infisical?

Yes, Infisical's core is open-source under the MIT license and can be self-hosted. The managed cloud service is also available with additional features.

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
Infisical: What is included in the Enterprise plan?

Enterprise plan includes SCIM, LDAP, approval workflows, external KMS/HSM support, and 99.99% SLA. Pricing is custom and determined by annual commitment.

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.
