Official CommandBox Dockerfiles

This is the repository for official Dockerfiles for Commandbox images

How it works

The Docker files in this repository can be used to create your own custom Docker container for running ColdFusion CFML applications on CommandBox. Leveraging CommandBox allows you to configure your entire ColdFusion CFML engine environment from a single server.json file in the root of your project.

Description

CommandBox allows you to configure your entire CFML engine environment from a single file in the root of your project. For more information on how to leverage CommandBox in developing and deploying your applications, see the official documentation.

Current CFML engines supported are:

Lucee: 4+ & 5+
Adobe ColdFusion 11+

You may also specify a custom WAR for deployment, using the server.json configuration.

Usage

This section assumes you are using the Official Docker Image

By default, the directory /app in the container is mapped as the 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 -p 8080:8080 -p 8443:8443 -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 a reference to begin your customizations. You can extend any of the base images and add your own additional functionality or modules. For example, to install the Ortus Couchbase extension for Lucee:

FROM ortussolutions/commandbox:lucee5

ARG COUCHBASE_EMAIL
ARG COUCHBASE_LICENSE_KEY
ARG COUCHBASE_ACTIVATION_CODE

# Copy Couchbase Extension into place for install
ADD http://lucee.ortussolutions.com/ext/couchbase-cache.lex /root/serverHome/WEB-INF/lucee-server/deploy/couchbase-cache.lex

# Seed Couchbase Extension License
ENV COUCHBASE_LICENSE_FILE /root/serverHome/WEB-INF/lucee-server/context/context/ortus/couchbase/license.properties
RUN touch "${CI_PROJECT_DIR}/build/license.properties" \
  && printf "email=${COUCHBASE_EMAIL}\n" >> ${COUCHBASE_LICENSE_FILE} \
  && printf "licenseKey=${COUCHBASE_LICENSE_KEY}\n" >> ${COUCHBASE_LICENSE_FILE} \
  && printf "activationCode=${COUCHBASE_ACTIVATION_CODE}\n" >> ${COUCHBASE_LICENSE_FILE} \
  && printf "serverType=Production\n" >> ${COUCHBASE_LICENSE_FILE}

# WARM UP THE SERVER WITH THE NEW EXTENSION
RUN ${BUILD_DIR}/util/warmup-server.sh

Environment Variables

The CommandBox Docker image supports 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 Variables

$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.

Server Configuration Variables

The following environment variables may be provided to modify your runtime server configuration. Please note that environment variables are case sensitive and, while some lower/upper case aliases are accounted for, you should use consistent casing in order for these variables to take effect.

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 )
APP_DIR - Application directory (web root). By default, this is /app. If you are deploying an application with mappings outside of the root, you would want to provide this environment variable to point to the webroot ( e.g. /app/wwwroot )
CFENGINE - Using the server.json syntax, allows you to specify the CFML engine for your container ( e.g. lucee@5 ). Defaults to the CommandBox default ( currently lucee@4.5)
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. You may instead add a .cfconfig.json file to the root of the APP_DIR and it will be picked up automatically. Note: The value CFCONFIG is aliased to this parameter, but is deprecated.
HEADLESS/headless - When set to true, a rewrite configuration will be applied which disallows access to the Lucee Admin or Coldfusion Administrator web interfaces for a secure deployment with no administrator access.
BOX_INSTALL/box_install - When set to true, the box install command will be run before the server is started to ensure any dependencies configured in your box.json file are installed
URL_REWRITES/url_rewrites - A boolean value, specifying whether URL rewrites will be enabled/disabled on the server. Rewrite configurations provided within the app's server.json file will supersede this argument.
USER - When provided the server process will run under the provided user account name
javaVersion - When provided the server will start on a custom JRE specified by the environment variable.

Docker Runtime Variables

$HEALTHCHECK_URI - Specifies the URI endpoint for container health checks. By default, this defaults to http://127.0.0.1:${PORT}/ at 20 second intervals, a timeout of 30 seconds, with 15 retries before the container is marked as failed. _Note: Since the interval, timeout, and retry settings cannot be set dynamically, if you need to adjust these, you will need to build from a Dockerfile which provides a new HEALTHCHECK command

Docker Secrets

Docker secrets can use two storage mechanisms:

Secret values stored as files on the host (non-swarm mode).
docker secret-managed key/value pairs (swarm mode).

To use secrets as variables in this image, a placeholder is specified (e.g., <<SECRET:test_docker_secret>>) as the variable's value. At run-time, the environment variable's value is replaced with the secret.

Example with a secret using host file storage:

version: '3.1'

services:

  sut:
    environment:
      - IMAGE_TESTING_IN_PROGRESS=true
      #- ENV_SECRETS_DEBUG # uncomment to debug the placeholder replacements
      # this is a placeholder that will be replaced at runtime with the secret value
      - TEST_DOCKER_SECRET=<<SECRET:test_docker_secret>>
    ...
    
secrets:
  test_docker_secret:
    # this is the file containing the secret value
    file: ./build/tests/secrets/test_docker_secret

Deployment

Because, with the exception of the CommandBox default engine of Lucee 5, the CFML server engines are downloaded and installed at container runtime. This can result in significant startup time increases ( even with Lucee 5 already downloaded in the base image, there is a time penalty for a "cold start" ). It is recommended that builds for production use employ an engine-specific variation for the build, which ensures the server is downloaded, in place, and warmed up on container start.

For a basic example, the following will suffice:

FROM ortussolutions/commandbox:lucee5

# Copy application files to root
COPY ./ ${APP_DIR}/

In many cases, you will have tier-specific builds, with custom configuration options. The following employs a build directory, which includes additional configuration files for tier-based deployments:

FROM ortussolutions/commandbox:lucee5

ARG CI_ENVIRONMENT_NAME

# Copy application files to root
COPY ./ ${APP_DIR}/

# Copy tier-only files over
COPY ./build/env/${CI_ENVIRONMENT_NAME}/tier/ ${APP_DIR}/

# Install our box.json dependencies
RUN cd ${APP_DIR} && box install

# Warm up and validate our server
RUN ${APP_DIR}/build/env/setup-env.sh

# Remove our build directory from our deployable image
RUN rm -rf ${APP_DIR}/build

# Set our healthcheck to a non-framework route - in this case we only need to know that CFML pages are being served
ENV HEALTHCHECK_URI "http://127.0.0.1:${PORT}/config/Routes.cfm"

In the above case, the setup-env.sh file might perform an additional server warmup and validation, where in the former case, the server was previously warmed up when the image was built.

Once your customized Dockerfile has has been built, you can run the generated image directly, or publish it to a private registry

About CommandBox

CommandBox is a standalone, native, modular CFML development and deployment tool for Windows, Mac, and Linux which provides a CLI for server orchestration, developer productivity, tool interaction, package management, application scaffolding, and some sweet ASCII art. It is open for extensibility for any ColdFusion (CFML) project and is written in CFML, allowing developers to easily write their own modules. It tightly integrates with the CFML open source hub ForgeBox, so developers can share modules world-wide.
