Docker support for SparkEd
March 21, 2019
Introducing docker support for SparkEd
This is part of minor releases on the SparkEd
You can now easily pull a docker image and run it without worrying about the package installations and other configurations.
We have provided a docker image that can easily be pulled from docker hub, this makes it for anyone to easily try out SparkEd.
About the docker implementation
What is docker? You may ask
According to OpenSource.com
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package.
Because of the ease in packaging everything together, we took this advantage to simplify the packaging.
The provied docker image relies on meteor launchpad, we provided a launchpad.conf that can be to support different configurations depending on your setup.
Why this setup ?
Simplification of configurations
Normally when you clone any nodejs based project you have to install packages yourself and other required setup, we created this image to make it easy for anyone who want to try out SparkEd.
How docker makes this easy is that the image is publicly shared on docker hub and anyone can just do docker pull olivierjm/spark then run it, and you will be good to go.
This abstracts away the need to configure lot of things on your end.
Continuous Deployment
We are currently using Travis as our CI/CD tool and these when combined they make it easy to automatically build and push on every push or PR merge. With these we are able to keep the image on docker hub updated with the latest changes without having to do it manually.
How to use the image
In the normal way you would run the image as follows
docker run imagename:tag in this case it would be docker run olivierjm/sparked:latest
but we would normally need to provide environment vairables that meteor can pick up and use like ROOTURL_, PORT, MONGOURL_ and any other envs that you might want to pass along.
If INSTALL_MONGO to true when building the image or in the launchpad.conf then you don’t need to set the MONGOURL_
docker run -d \
-e ROOT_URL=http://your_url \
-p 80:3000 \
yourname/sparked:tagcheck http://your_url in your browser if the image run successfully then you should be able to have everything working.
Watch out for v2 release which will be coming out soon.
