dozzle

name	dozzle
description	Direct Dozzle API workflow for the real-time Docker container log viewer. Use when the user wants to inspect Dozzle health, version, containers, logs, authentication failures, session-cookie refresh, auth setup, or Dozzle MCP. Uses `DOZZLE_URL` and optional `DOZZLE_SESSION_COOKIE`; do not route through Lab MCP or `lab dozzle`.

Dozzle

Real-time Docker container log viewer.

How to call it

Use Dozzle's HTTP API directly. Do not use Lab MCP, mcp__lab__dozzle, lab dozzle, or labby dozzle; those paths are stale for this service.

Configuration

Read connection values from the environment when available:

DOZZLE_URL                 # base URL, for example http://host:8080
DOZZLE_SESSION_COOKIE      # optional raw Cookie header value

If the shell environment is not already populated, ~/.lab/.env may contain these values. Source it only inside a subshell and suppress source output.

Security Model

Dozzle's local web API routes are implementation details, not a stable public REST contract. Use them as best-effort operational probes and keep calls read-only unless the user explicitly asks for a mutating action.

Check the root config__json for authProvider, enabled shell/actions, and host inventory. If authProvider is none, access control is provided only by the surrounding network/proxy boundary. Treat direct Tailnet or LAN URLs as bypasses around Authelia/forward-proxy auth unless ACLs restrict them.

Dozzle can reach Docker hosts, and Docker socket access is highly privileged. If shell/actions/download are enabled, prefer an authenticated/proxied path and do not invoke shell or action endpoints without explicit user intent.

Auth

Dozzle may run with no auth or with a browser session cookie. Probe without a cookie first when DOZZLE_SESSION_COOKIE is unset. When the cookie is set, pass it as a Cookie header through stdin config, not as a command-line argument:

(
  set +x
  set -a; . ~/.lab/.env >/dev/null 2>&1 || true; set +a
  /usr/bin/curl -fsS --config - "$DOZZLE_URL/api/version" <<EOF
header = "Cookie: ${DOZZLE_SESSION_COOKIE}"
EOF
)

Never echo the cookie or include it in logs. If a request returns 401 or 403, help the user refresh the browser session cookie without pasting it into chat.

Common API Checks

Use /usr/bin/curl if shell startup or sourced env files alter PATH.

(
  set +x
  set -a; . ~/.lab/.env >/dev/null 2>&1 || true; set +a
  /usr/bin/curl -fsS "$DOZZLE_URL/api/version"
  /usr/bin/curl -fsS "$DOZZLE_URL/" | sed -n '/config__json/,/<\\/script>/p'
)

For configuring Dozzle auth providers or MCP, read references/auth-mcp.md.

When NOT to use this skill

• The user is asking about a different lab service - load that service's skill instead.
• The user is asking about Lab MCP, Lab CLI internals, or gateway behavior - use the Lab/operator skill instead.
