Containers

uniTerm has a built-in container management interface supporting Kubernetes cluster management and the Docker / Podman / nerdctl / WSLC container runtimes. Manage cluster resources and container images on the local machine or on remote hosts over SSH.

Kubernetes

Connection Parameters

Parameter	Description
Source	Local file (specify a kubeconfig path, with a file picker button) or Kubeconfig text (collapsed by default; click "Show Config" to expand and paste the content, with "Import from file" available)
Context	Select a context from the kubeconfig; click "Reload" to refresh the list
Namespace	The default namespace to view; check "All namespaces" to browse the whole cluster
Skip TLS verification	Skip API Server certificate validation (insecure, for self-signed test environments only)
SSH Tunnel	Optional. Access an internal cluster API through an SSH jump host

After filling in the fields, click "Test Connection" to verify the kubeconfig and network reachability.

Cluster Overview

The connection opens on the cluster overview, showing the whole cluster at a glance:

• Cluster info — Kubernetes version, current Context, namespace count
• Nodes — Total node count and readiness (not-ready nodes highlighted)
• Resource summary — Counts of workloads / networking / storage & config resources
• Pod status — Distribution by run state
• Usage — Cluster CPU / memory actual usage vs. requests (requires metrics-server installed in the cluster)
• Recent events — Recent warning events; clicking a resource stat jumps to its resource list

Resource Browsing

The left tree panel groups cluster resources by category, watches for changes, and refreshes automatically:

Group	Resources
Workloads	Pods, Deployments, StatefulSets, DaemonSets, ReplicaSets, Jobs, CronJobs, HPAs
Network	Services, Ingresses, Endpoints, NetworkPolicies, Gateways, HTTPRoutes, GRPCRoutes
Config	ConfigMaps, Secrets, ResourceQuotas, LimitRanges
Storage	PVCs, PVs, StorageClasses
RBAC	ServiceAccounts, Roles, RoleBindings, ClusterRoles, ClusterRoleBindings
Cluster	Nodes, Namespaces, Events, CRDs

• Top filter — Filter in real time by name, status, namespace, and other columns
• Health highlighting — Not-ready Pods, under-replicated workloads, and NotReady nodes are highlighted row-wide
• Live metrics — Pod and Node lists show CPU / memory usage and its percentage of requests/limits (requires metrics-server installed in the cluster)

Resource Actions

After selecting a resource, the right-click menu or inline action buttons provide the following (varies by resource type):

• Detail — A side drawer shows the full metadata, Spec, Status, and other fields
• Edit — Edit the resource YAML directly and apply
• Create — Create resources from a built-in YAML template
• Scale — Change the replica count of a Deployment / StatefulSet / ReplicaSet
• Restart — Rolling-restart a workload
• View Pods — Jump to the Pod list associated with the workload/node
• Cordon / Drain — Mark a node unschedulable or evict its Pods
• Delete — Delete after confirmation, with optional force delete (skip graceful termination)

Pod Logs and Terminal

• Logs — Follow Pod logs in real time, with pause/resume, timestamps, previous container, auto-scroll, wrap, and clear
• Terminal — Exec directly into a Pod container for an interactive shell

Container File Browser

For running Pods, a dual-pane file browser can be opened to browse the container's filesystem directly, uploading / downloading files between local and container. Transfers are tracked in a task list (running / done / failed) — no need to run kubectl cp by hand.

Container Engines

Four runtimes are supported: Docker, Podman, nerdctl (containerd), and WSLC (Windows WSL2 Container, Windows only). Choose the subtype when creating a new connection.

Connection Parameters

Parameter	Description
Transport	Remote host (SSH) (default) reuses an existing SSH connection — inheriting its credentials and jump host configuration — to manage containers on a remote host; Local machine uses the container runtime installed on this machine
SSH Connection	When the transport is remote host, select a saved SSH connection as the channel

nerdctl supports switching the containerd namespace from the top bar. The WSLC runtime does not offer the "Restart" or "Rename" actions; its image layers come from image inspect (layer digests only — the CLI has no history command).

Container Management

The left tree panel switches between the "Overview", "Containers", and "Images" views.

The overview shows runtime and host info (client / server version, kernel, storage driver, CPU, memory) plus container and image counts.

The container list shows name, image, state, port mappings, and creation time, with the following actions:

• Lifecycle — Start, stop, restart, pause, unpause
• Exec — Enter an interactive terminal in the container
• Files — Open the container file browser to browse a running container's filesystem and upload / download files (same as the Kubernetes container file browser described above)
• Logs — View container log output
• Rename — Change the container name
• Remove — Remove the container after confirmation
• Detail — View overview, command, network, mounts, environment, and state
• New Container — Create a container by specifying image, name, port mappings, volumes, environment variables, restart policy, and command

Image Management

The image list shows repository, tag, ID, and size, and supports:

• Pull — Pull an image from a registry by name (e.g. nginx:latest)
• Remove — Remove the image after confirmation
