This is a documentation explaing dockerization of an api caching project in python. This project is designed with an nginx proxy loadbalancer to loadbalance the traffic among api containers and a Redis cache container for api caching. All the communications between the containers are through a bridge network inside the host server.
I used ipstack API in this python application as a demo. This API will show you the Geolocation of IP addresses.
- IP-Location finding website (Python) (Just a demonstration)
- Easy to migrate everywhere
- Container load balanced (Nginx)
- All containers are spin up with a single command
- 5 Containers for LAMP (IP-Stack, Redis, Nginx(Load Balancer))
- 1 Network (For Container interconnecting)
- Need to install docker and docker-compose
- You have a basic knowledge of what is docker.
- You have a basic knowledge of what is ipstack and how it's working
- Need an IP stack Login and API for location finding
- Need to add apikey file before running the script. So, please find the IP stack URL and grab the key and change the same on "env.dev"
Please refer the doc for docker installation
yum install docker -y yum install git -yPlease refer the doc for docker-compose installation
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/bin/docker-compose sudo chmod +x /usr/bin/docker-compose docker-compose version you guys can use play with Docker which includes pre-installed docker and compose. It looks like a terminal and it's built from alpine OS. So, it's just used for learning purpose so who you guys can use 4hrs session without any additional installation.
Please go through the ipstack and click "GET FREE API KEY" on the top right corner.
- Clone application from GitHub
git clone https://github.com/dilshadkp/api-caching-with-nginx-proxy.git cd api-caching-with-nginx-proxy- Add your API KEY in env.txt
vim env.txtIPSTACK_KEY="enter-your-key-here(without any double quotes)"- Execute the docker-compose.yml
