Communication between applications in Docker
-
Lets establish container connectivity for the nopCommerce
- Lets quickly write a dockerfile for nopcommerce
FROM alpine:3.18.2 AS extractor

CMD ["dotnet", "Nop.Web.dll"]
- Create a docker image with name
nop:4.60.3 - Lets create a bridge network with cidr range
192.168.0.0/24
- Lets create a mysql container with on nop-net network
- username => nop
- pwd => nop@123
- root password => nop@123
- database name => nopdb
docker container run --name nopdb -d -e MYSQL_ROOT_PASSWORD=nop@123 -e MYSQL_DATABASE=nopdb -e MYSQL_USER=nop -e MYSQL_PASSWORD=nop@123 --network nop-net mysql:8
- Lets inspect ip address for this container
docker network inspect nop-net
* note: when you practice ensure you create and mount volume
* Lets try creating nop container in the same network
docker container run -d --name nop1 --network nop-net -p 32000:5000 nop:4.60.3
- Lets inspect network again
- Now lets configure the application by accessing it
- Now enter the data base details
- Once the installation is complete the nop container will be stopped, kindly start it
-
Now access the application
-
Exercise:
- Create a multistage build for nopCommerce
- Try it with mysql db and postgres db
- Optional try with sql server
sudo docker pull mcr.microsoft.com/mssql/server:2022-latest
Docker compose
- Lets try running nop commerce in a system in easier way
- consider the nopCommerce code from here Refer Here
- Refer Here for the yaml file created
- Clone the git repo and cd into it
- Then execute
git checkout compose_intro
docker compose up -d
- Note: YAML Tutorial Refer Here
