Docker commands

docker.ps

docker build -t myapp:2.0 .

docker run --name myapp_2.0 -d -p 7777:7000 myapp:2.0
docker run --name myapp_2.0 -it -p 7777:7000 myapp:2.0  
## -it is short for --interactive + --tty when you docker run with this command.
## it would take you straight inside of the container,
## where -d is short for --detach which means you just run the container and 
## then detach from it so basically you run container in the background.
## edit : so if you run docker container with -itd it would run the-it options and detach you from the container, 
## so your container still running in the background even without any default app to run.

docker kill myapp_2.0
docker rm myapp_2.0
docker run --name myapp_2.0 -d -p 7777:7000 myapp:2.0
## docker run --rm -p ... would prevent requiring docker rm previously

docker run --rm -p 4000:5000 -p 4001:5001 -p 4002:30001 -v /user/bigdata:/user/bigdata/ my_app:2.0
## -v is used to map folder outside docker to a path inside it. 
## Good for config files, or huge datasets, indexs or models that shouldn't be inside the docker.
## -p <port host machine>:<port inside docker to expose>

docker run -it myapp:2.0 bash
## opens bash inside container

docker tag myapp:2.0 <target account on dockerhub>/myapp:2.0
## tag
docker push  <target account on dockerhub>/myapp:2.0
## upload
