--- title: Stack Management description: Create, deploy, control, and remove Docker Compose stacks. --- A **stack** in Sencho is a Docker Compose project: a directory inside your `COMPOSE_DIR` that contains at least a `compose.yaml` (or `docker-compose.yml`) file. Sencho automatically discovers every subdirectory as a stack. Create New Stack dialog ## Creating a stack Click **Create Stack** in the left sidebar. Enter a name and click **Create**. **Naming rules:** - Lowercase letters, numbers, and hyphens only (e.g. `my-app`, `nextcloud`) - No spaces or special characters - Must be unique; duplicates are rejected Sencho creates a new directory inside `COMPOSE_DIR` with a blank `compose.yaml` file. You'll land in the editor automatically. ## Convert from a docker run command If you have a `docker run` command handy (from a README, a forum post, or your shell history), Sencho can turn it into a ready-to-deploy `compose.yaml` without hand translation. Open the **Create New Stack** dialog and switch to the **From Docker Run** tab. Create stack dialog on the From Docker Run tab ### How to use it 1. Enter a **Stack Name**. Same rules as the Empty tab (lowercase, hyphens, unique). 2. Paste your full command into **Paste your docker run command**. The whole command should be on one logical line; line continuations with `\` are fine. 3. Click **Convert**. Sencho parses the command and shows the resulting compose YAML in a read-only preview below. 4. Review the YAML. If it looks right, click **Create Stack**. Sencho creates the stack directory and writes the converted YAML into `compose.yaml`. 5. The editor opens on the new stack. Click **Start** to deploy it. Converted compose YAML preview before creating the stack Newly created stack loaded in the editor after conversion ### Supported flags The converter handles the flags you reach for most often: | Flag | Purpose | |------|---------| | `-d` / `--detach` | Detached mode (implied by compose) | | `--name` | Container name | | `-p` / `--publish` | Port mappings (`host:container`) | | `-v` / `--volume` | Volumes and bind mounts | | `-e` / `--env` | Environment variables | | `--env-file` | Env file reference | | `--restart` | Restart policy (`no`, `always`, `unless-stopped`, `on-failure`) | | `--network` | Attach to a named network | | `--label` | Container labels | | `--user` | Run as a specific user | | `--workdir` | Set the working directory | | `--entrypoint` | Override the entrypoint | | `--cap-add` / `--cap-drop` | Linux capabilities | | `--privileged` | Privileged mode | | `--read-only` | Read-only root filesystem | | `--tmpfs` | Temporary filesystem mount | The image tag is taken from the final positional argument (for example `nginx:alpine`). Any trailing command arguments are preserved as the service `command`. ### Troubleshooting Error toast shown when the converter cannot parse the input If the converter cannot produce a usable compose file, the request fails with a clear error toast. Common causes: - **Not a docker run command.** The input must begin with `docker run` and include an image reference. Free-form text, `docker compose` commands, and shell pipelines are rejected. - **Unrecognized flag.** The parser supports the flags listed above. Rare flags (such as `--userns`, `--ipc`, custom runtime options) may not be recognized. Remove the flag, convert the rest, and add it back by hand in the editor. - **Quoting issues.** Multi-line commands with embedded quotes sometimes confuse the parser. Paste the command as a single line with escaped quotes, or simplify the command first. - **Command is too long.** The endpoint accepts commands up to 8192 characters. Longer inputs are rejected; trim anything you do not need and convert in pieces. When a flag is not supported, paste the output you do get into the **Empty** tab as a starting point and fill in the rest by editing `compose.yaml` directly. ## The stack list All discovered stacks appear in the left sidebar. Each shows a color-coded status indicator: | Indicator | Meaning | |-----------|---------| | `UP` (green) | All containers running | | `DN` (red) | One or more containers exited | | No indicator | No containers / status unknown | Use the **search box** above the list to filter stacks by name. ## Deploying a stack Select a stack and click **Start** (or **Deploy** from the context menu) in the stack header. This runs `docker compose up -d`, pulling images if needed and creating or recreating containers. Stack editor with control buttons ## Controlling a running stack The stack header shows different actions depending on whether the stack is running or stopped. **When running:** | Button | Command | What it does | |--------|---------|--------------| | **Stop** | `docker compose stop` | Stops containers without removing them. State is preserved. | | **Restart** | `docker compose restart` | Restarts all containers in the stack. | | **Update** | `docker compose pull` + `up -d` | Pulls the latest image tags and recreates containers. | | **Rollback** | Restores backup | Reverts compose and env files to the pre-deploy snapshot and redeploys. Only shown when a backup exists (Skipper+). | | **Delete** | `down --volumes` + removes files | Stops and removes containers and volumes, then deletes the stack directory. | **When stopped:** | Button | Command | What it does | |--------|---------|--------------| | **Start** | `docker compose up -d` | Starts the stack. | | **Update** | `docker compose pull` + `up -d` | Pulls the latest image tags and recreates containers. | | **Delete** | Removes files | Deletes the stack directory. | **Delete** is irreversible. It removes the stack directory, including `compose.yaml`, `.env`, and any bind-mounted files stored there. Back up important files before deleting. Stack directories often contain root-owned files, either because Docker Compose creates them, or because the stacks were originally set up outside of Sencho with `sudo`. Sencho handles this automatically: if a normal deletion fails due to permissions, it uses Docker to clean up root-owned files. No manual intervention is needed in the standard setup. ## Stack context menu Right-click any stack in the sidebar to open the context menu. The menu adapts to the stack's current state; only relevant actions are shown. **Running stack:** Context menu for a running stack **Stopped stack:** Context menu for a stopped stack ### Available actions - **Alerts** - configure metric-based alerting rules for this stack - **Labels** - assign organizational labels (Skipper+) - **Check for updates** - manually trigger an image update check - **Open App** - open the stack's web interface in a new tab (only shown when the stack is running and exposes a web port) - **Deploy** - start the stack (shown when stopped) - **Stop** - stop all containers (shown when running) - **Restart** - restart all containers (shown when running) - **Update** - pull latest images and recreate containers (shown when running) - **Delete** - stop and remove the stack (admin only) All actions are disabled while another operation is in progress on that stack. ## Scanning for stacks If you place Docker Compose files directly into the stacks directory (for example, via `scp`, a file manager, or the command line), you can import them without going through the full "Create Stack" flow. Click the **folder-search icon** next to the "Create Stack" button in the sidebar. Sencho scans the configured stacks directory and reports what it finds: Scan stacks folder button in the sidebar - **New stacks detected** - a success notification lists the newly discovered stack names, and they appear immediately in the sidebar - **Stacks removed from disk** - an informational notification lists stacks that are no longer present in the directory - **No changes** - a notification confirms no new stacks were found Any subdirectory inside your `COMPOSE_DIR` that contains a `compose.yaml`, `compose.yml`, `docker-compose.yaml`, or `docker-compose.yml` file is recognized as a valid stack.
