CommandBox Docker Deployments

CommandBox also provides an official Docker image, which allows you to leverage its capability to orchestrate live servers in multi-tier deployments.

Since, CommandBox allows you to configure your entire CFML engine environment from a single file in the root of your project, packaging or mounting your CFML application in to a running CommandBox image container allows you to stand up your application in Docker containers in a matter of seconds.

Usage

This section assumes you are using the Official Docker Image

By default, the directory /app in the container is mapped as Commandbox home. To deploy a new application, first pull the image:

docker pull ortussolutions/commandbox

Then, from the root of your project, start with

docker run -p 8080:8080 -p 8443:8443 -v "/path/to/your/app:/app" ortussolutions/commandbox

By default the process ports of the container are 8080 (insecure) and 8443 (secure - if enabled in your server.json) so, once the container comes online, you may access your application via browser using the applicable port (which we explicitly exposed for external access in the run command above). You may also specify different port arguments in your run command to assign what is to be used in the container and exposed. This prevents conflicts with other instances in the Docker machine using those ports:

docker run -expose-list 80 443 -e "PORT=80" -e "SSL_PORT=443" -v "/path/to/your/app:/app" ortussolutions/commandbox

To create your own, customized Docker image, use our Dockerfile repository as the baseline to begin your customizations.

Environment Variables

The CommandBox Docker image support the use of environmental variables for the configuration of your servers. Specifically, the image includes the cfconfig CommandBox module, which allows you to provide custom settings for your engine, including the admin password.

• $PORT - The port which your server should start on. The default is 8080.

• $SSL_PORT - If applicable, the ssl port used by your server The default is 8443.

• $CFENGINE - Using the server.json syntax, allows you to specify the CFML engine for your container

• $HEALTHCHECK_URI - Specifies the URI endpoint for container health checks. By default, this is set http://127.0.0.1:${PORT}/ at 1 minute intervals with 5 retries and a timeout of 30s

• $cfconfig_[engine setting] - Any environment variable provided which includes the cfconfig_ prefix will be determined to be a cfconfig setting and the value after the prefix is presumed to be the setting name. The command cfconfig set ${settingName}=${value} will be run to populate your setting in to the $SERVER_HOME_DIRECTORY.

• $cfconfigfile - A cfconfig-compatible JSON file may be provided with this environment variable. The file will be loaded and applied to your server. If an adminPassword key exists, it will be applied as the Server and Web context passwords for Lucee engines

• $SERVER_HOME_DIRECTORY - When provided, a custom path to your server home directory will be assigned. By default, this path is set as /root/serverHome ( Note: You may also provide this variable in your app's customized server.json file )
