A read-only terminal UI for inspecting containerd resources. Browse images, containers, tasks, snapshots, and events — without modifying anything.
Experimental — under active development. Keybindings and features may change.
- Images — multi-platform index/manifest tree with layer counts and sizes
- Snapshots — parent-child chain with snapshotter selection
- Containers — sandbox/container grouping with runtime spec inspection
- Tasks — running processes including exec sessions, with PID, cmdline, cgroups, and namespaces
- Events — live stream of containerd lifecycle events
- Live updates — subscribes to containerd events and refreshes automatically
- Cross-tab navigation — jump between related resources (container → snapshot, task → container)
- Read-only — nerdview only reads from containerd. It will never create, delete, or modify any resources.
- Linux only — currently only implemented and tested on Linux.
