Docker
The OHIF source code provides a Dockerfile to create and run a Docker image that containerizes an nginx web server serving the OHIF Viewer.
The OHIF Viewer Docker image for the v3-stable
branch is not yet published. The available image in Docker Hub is based on the master
branch.
Prequisites​
The machine on which to build and run the Docker container must have:
- All of the requirements for building a production version of OHIF.
- A checked out branch of the OHIF Viewer.
- Docker installed.
Building the Docker Image​
The docker image can be built from a terminal window as such:
Switch to the OHIF Viewer code root directory.
Issue the following docker command. Note that what follows
-t
flag is the{name}:{tag}
for the Docker image and is arbitrary when creating a local Docker image.docker build . -t ohif-viewer-image
Running the Docker Container​
Once the Docker image has been built, it can be run as a container from the command line as in the block below. Note that the last argument to the command is the name of the Docker image and the table below describes the other arguments.
Flag | Description |
---|---|
-d | Run the container in the background and print the container ID |
-p {host-port}:{nginx-port}/tcp | Publish the nginx listen port on the given host port |
--name | An arbitrary name for the container. |
docker run -d -p 3000:80/tcp --name ohif-viewer-container ohif-viewer-image
Configuring the nginx
Listen Port​
The Dockerfile and entry point use the ${PORT}
environment variable as the port that the nginx
server uses to serve the web server. The default value for ${PORT}
is 80
. One way to set this environment variable is to use the -e
switch when running the container with docker run
. The block below gives an example where the listen port is set to 8080
and publised on the host as 3000
.
docker run -d -e PORT=8080 -p 3000:8080/tcp --name ohif-viewer-container ohif-viewer-image
