Managing the Server with Ghostwriter CLI

How to use Ghostwriter CLI to monitor and manage your Ghostwriter installation

Using Ghostwriter CLI to Manage the Server

Ghostwriter CLI can handle just about anything you might need or want to do with your Ghostwriter installation. Running the tool with the help command–or no command–will print the latest usage information.

The following sections explain some of the core functionality.

By default, all commands target a production environment. Provide the --dev if you're interacting with a development environment. Every command can accept the --dev flag.

Managing the Server Configuration

The config command is your Swiss Army knife when managing your server configuration. If you don't provide any subcommands or arguments, the command prints your current configuration values (the contents of your server's DotEnv file).

You can pull and set configuration values with config. Use config get to fetch a specific value or set of values. Use config set to change a value.

There are also several subcommands to help you manage hostnames and origins you trust: allowhost, disallowhost, trustorigin, and distrustorigin. Use these subcommands to adjust those values, as the Quick Start guide describes.

Customizing Your Installation

Managing Docker Containers

Ghostwriter CLI's containers command contains the following subcommands:

• build : Rebuild the containers (not the data volumes)

• up : Bring up Ghostwriter containers

• down : Bring down Ghostwriter containers

• start: Start all stopped services and restart any running services

• stop: Stop all running services

• restart : Stop and restart all services

If you need to check which containers are running, issue the running command. This command lists all running containers related to Ghostwriter. The output will look something like this (edited for easier display):

$ ./ghostwriter-cli running

The Status column shows the uptime and health of the service. If you see an unhealthy status that the service failed a health check and may not work properly. Learn more about health checks here: Health Monitoring

You can use the logs command to view a particular container's recent log events. The command requires the name of a running container. Valid container names are:

• all

• django

• graphql

• nginx

• postgres

• redis

With all, logs from all running containers will be returned. By default, logs will return up to 500 lines. You can use the --lines flag to adjust how many lines you want to retrieve.

$ ./ghostwriter-cli logs django
