Packer is HashiCorp tool automating machine image builds. Define image in HCL/JSON, Packer installs OS, patches, dependencies, tools. Output: AWS AMI, Azure VHD, GCP image. Instead of manually spinning up 100 servers, boot from your Packer image in 2 min. Mastery takes 3-4 weeks. DevOps and infrastructure teams use Packer daily. Engineers managing infrastructure-as-code earn 20-30% premium; Packer expertise is part of that suite.

Packer Infrastructure Templates là gì

Packer is an open-source tool that automates machine image creation. You define a template (HCL or JSON) specifying base OS, packages to install, configurations, and tests. Packer builds an image: boots a temporary instance, runs your provisioning scripts, tests, then captures the image for reuse. Output: AWS AMI (Amazon Machine Image), Azure VHD, GCP Image, Vagrant box. Share across team. Deploy 1000 servers from one image in seconds.

❓ Câu hỏi thường gặp

▶What's the difference between Packer and Docker?
Docker = containerized apps (smaller, fast). Packer = full machine images (OS + everything). Use Docker for microservices. Use Packer for traditional applications, databases, desktop environments. Both can coexist (Packer builds image, Docker runs in it).
▶How do I keep Packer images fresh with security patches?
Run Packer builds weekly (cron job). Each build pulls latest patches (apt update && apt upgrade). Output new image version. Old images tagged as deprecated. New deployments use latest image with current patches.
▶Can I build Packer images in CI/CD pipeline?
Yes. Commit to repo → CI/CD detects change → runs Packer → tests image → uploads to AWS → tags with commit SHA. Infrastructure changes flow through git like code.
▶How do I test a Packer image before using it?
Boot an instance from image. Run smoke tests (Can I SSH? Does app start? Can I reach it?). If tests pass, mark as 'approved'. If fail, iterate on Packer template and rebuild.
▶What's the difference between Packer and Terraform?
Packer = build images. Terraform = provision infrastructure using images. Packer outputs image ID. Terraform uses that image ID to spawn 100 instances. Complementary tools.
