Docker 2
Build Container
RUN command
RUN su-exec volpara git clone https://github.com/bibble235/aports
Copying from on container
Given the container
FROM ubuntu:18.04 AS opencv_build
Copying can be done using
COPY --from=opencv_build /usr/local/opencv/ /usr/local/
Creating a docker postgres image
This exposes the default port 5432 for postgres
docker run --name postgresq-spring -e POSTGRES_USER=iain -e POSTGRES_PASSWORD=password -p 5432:5432 -v /data:/var/lib/postgresql/data -d postgres:alpine
The -d is to run the container in the background
The postgres:alpine is the image name
The -p is the port to expose which is the default for postgress
The -v is where the data will be stored
Running a Container
Sample for running a container with name test, ip 172,18.0.11, network to run on as billnet, capital P to expose the port (not for production), remove container when exit, it to have the errors go to the host console, and ps/dataservice for the image name
docker run --name test --ip=172,18.0.11 --net=billnet -P --rm -it ps/dataservice
