IT and DevOps flashcards: Linux, Bash, Vim, networking, security, Docker, Kubernetes, AWS and Terraform
Operations work rewards instant recall: the right find flags, the port behind a service, the subnet a host sits in, the kubectl command that shows why a Pod keeps crashing. These decks cover the commands and concepts that certifications like LPIC-1 test and that on-call shifts demand.
- Exam-alignedThe Linux deck follows LPIC-1 topics: filesystems, permissions, packages, boot targets, users and cron.
- Commands you can runAnswers are real, highlighted commands and manifests, not vague definitions.
- From one server to a clusterLinux and networking basics through Docker images and Kubernetes objects.

50 cardsHow spaced repetition works
- Step 1See a cardRecall the answer before you flip it. Effortful recall is what builds memory.
- Step 2Grade yourselfAgain, Hard, Good or Easy. Each answer sets when the card comes back.
- Step 3Review just in timeCards return right before you would forget them: minutes, then days, then months.
Frequently asked questions
Does the Linux deck cover LPIC-1?
It follows the LPIC-1 (101 and 102) topics, from find, grep and permissions to fstab, systemd targets, package managers and cron. It is a review aid, so pair it with hands-on practice.
Are the commands for Debian or Red Hat?
Both. Package management covers dpkg and apt as well as rpm and dnf, and systemd works the same on every major distribution.
Which networking topics are included?
The OSI and TCP/IP models, TCP and UDP, common ports, subnetting and CIDR, DNS records, DHCP, ARP and IPv6 basics.
