Docker is a software container platform that integrates easily into Hotel.
A Dockerfile is used to create a single container. Here is an example:
FROM httpd:2.4
COPY ./public-html/ /usr/local/apache2/htdocs/
To build this image, run the following in the application directory:
docker build -t my-apache2 .
To use Hotel for this example, run the following in the application directory:
hotel add 'docker run -dit --name my-running-app my-apache2'
Compose is a tool for defining and running multi-container Docker applications. Here is a simple example:
version: '3'
services:
web:
build: .
ports:
- "5000:5000"
This binds the internal port 5000 on the container to port 5000 on the host machine. To build this image, run the following:
docker-compose build
To use Hotel for this, run the following in the application directory:
hotel add 'docker-compose up' -p 5000
