Overview
Designed custom container environments in C, leveraging filesystem isolation, PID namespaces, and cgroup-based resource provisioning to enable controlled execution of multiple processes in isolated environments.
Key Features
- Filesystem Isolation: Chroot and mount namespaces for process isolation
- PID Namespaces: Separate process trees for each container
- Cgroup Resource Provisioning: CPU, memory, and I/O resource limiting
- Container Networking: TCP port forwarding and peer communication between containers
- Container Management: Automated container creation, execution, and lifecycle management
Technologies
- C for systems-level container implementation
- Linux namespaces (mount, pid, network)
- Cgroups for resource control
- Socket programming for container networking
Implementation Tasks
- Task 1-4: Progressive implementation of container features
- Filesystem isolation and namespace creation
- Process management and signal handling
- Resource provisioning and cgroup configuration
- Networking and inter-container communication
Learning Outcomes
- Deep understanding of Linux containerization
- Namespace and cgroup internals
- Systems-level programming in C
- Container orchestration concepts
- Network namespace management
