Fixing issue with startup of .net application
-
Refer Here for the Dockerfile
- Refer Here the document to host the .net application on 0.0.0.0
Setting Environment Variables in the container
- ENV instruction Refer Here
- This instruction adds environmental variable in the container and it also allows us to change environmental variables while creating containers
- Refer Here for the changes done to include environmental varibles
- docker container exec will allow us to execute commands in the container
docker container exec -it <c-name> <shell>will allow us to login into container
- ARG instruction allows us to set the values while building the image Refer Here
- Refer Here for the BUILD ARGS added
- Build args can be set while creating images. BUILD ARG can be used by using
${ARG_NAME}. - We have build two images by changing the HOME_DIR and DOWNLOAD_URL Build args
docker image build --build-arg DOWNLOAD_URL=nopCommerce_4.60.2_NoSource_linux_x64.zip -t nop:1.0.2 .
docker image build --build-arg HOME_DIR=/publish -t nop:1.0.0 .
- USER: Refer Here
- Refer Here for the changes done to add a non root user to run the nop commerce application.
Exercise:
- Gameof life application:
- This requires java 8
- this requires tomcat 8 or 9
- copy the gameoflife.war application into webapps folder of tomcat Refer Here
- This runs on port 8080
