How to create an API Rest using json-server and Docker
Before you begin
In this tutorial will learn how to create an API Rest using json-server and Docker. A Linux machine and Docker will be required to follow this tutorial.
Create a Docker image
Dockerfile:
FROM ubuntu:14.04
ENV tmp_dir /tmp
WORKDIR ${tmp_dir}
RUN apt-get update \
&& apt-get install -y curl wget vim \
&& curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - \
&& apt-get install -y nodejs
RUN npm install -g json-server
#ADD test.json /tmp
RUN echo '{"cars":[{"id":1,"brand":"opel","model":"corsa"},{"id":2,"brand":"ford","model":"fiesta"}]}' > /tmp/test.json
ADD entrypoint.sh ${tmp_dir}
RUN chmod +x entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]
Run container/server
Commands to build and run the server on port 8080:
# Build previous image
$ docker build -t jsonserver .
# Run container
$ docker run --rm --name jsonserver-container -p 8080:8080 -it jsonserver
Copy JSON file
By default the image contains a /tmp/test.json with example of cars but you can overwrite it using a local/remote JSON file.
Remote file:
$ docker run --rm --name jsonserver-container -p 8080:8080 -e "file=https://REMOTE_FILE.json" -it jsonserver
Local file:
$ docker cp MY_LOCAL_FILE.json jsonserver-container:/tmp/test.json
Test API
HTTP calls examples based on the following test.json:
{
"cars": [
{
"id": 1,
"brand": "opel",
"model": "corsa"
},
{
"id": 2,
"brand": "ford",
"model": "fiesta"
}
]
}
GET
$ curl http://0.0.0.0:8080/cars
POST
$ curl -i -H "Accept: application/json" -H "Content-type: application/json" -d '{"brand":"seat","model":"ibiza"}' -X POST http://0.0.0.0:8080/cars $ curl -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d '{"brand":"seat","model":"ibiza"}' http://0.0.0.0:8080/cars
PUT
$ curl -H "Accept: application/json" -H "Content-Type: application/json" -X PUT -d '{"brand":"opel","model":"astra"}' http://0.0.0.0:8080/cars/1
