docker container run -d -p 80:80 --name nginx-server nginx- Looked for image called nginx in image cache
- If not found in cache, it looks to the default image repo on Dockerhub
- Pulled it down (latest version), stored in the image cache
- Started it in a new container
- We specified to take port 80- on the host and forward to port 80 on the container
- We could do "$ docker container run --publish 8000:80 --detach nginx" to use port 8000
- We can specify versions like "nginx:1.09"

docker container logs [NAME]# List processes running in container
docker container top [NAME]Docker containers are often compared to virtual machines but they are actually just processes running on your host os. In Windows/Mac, Docker runs in a mini-VM so to see the processes youll need to connect directly to that. On Linux however you can run "ps aux" and see the processes directly
# List the images we have pulled
docker image ls# We can also just pull down images
docker pull [IMAGE]# Remove image
docker image rm [IMAGE]# Remove all images
docker rmi $(docker images -a -q)- Images are app bianaries and dependencies with meta data about the image data and how to run the image
- Images are no a complete OS. No kernel, kernel modules (drivers)
- Host provides the kernel, big difference between VM

FROM - The os used. Common is alpine, debian, ubuntu
-
COPY # Copies files from host to container
-
ADD # Copies files from host to container
-
ENV - Environment variables
-
ARG - Environment variables
-
CMD - Final command run when you launch a new container from image
-
ENTRYPOINT - Final command run when you launch a new container from image
-
RUN - Run commands/shell scripts, etc
-
EXPOSE - Ports to expose
-
WORKDIR - Sets working directory (also could use 'RUN cd /some/path')
# From the same directory as Dockerfile
docker image build -t [REPONAME] .- If you re-run the build, it will be quick because everythging is cached.
- If you change one line and re-run, that line and everything after will not be cached
- Keep things that change the most toward the bottom of the Dockerfile

docker container inspect mysql- You will also see the volume under mounts
- Container gets its own uniqe location on the host to store that data
- Source: xxx is where it lives on the host
# Check volumes
docker volume lsThere is no way to tell volumes apart for instance with 2 mysql containers, so we used named volumes
# Named volumes (Add -v command)(the name here is mysql-db which could be anything)
docker container run -d --name mysql -e MYSQL_ALLOW_EMPTY_PASSWORD=True -v mysql-db:/var/lib/mysql mysql# Inspect new named volume
docker volume inspect mysql-db- Can not use in Dockerfile, specified at run time (uses -v as well)
- ... run -v /Users/brad/stuff:/path/container (mac/linux)
- ... run -v //c/Users/brad/stuff:/path/container (windows)
TIP: Instead of typing out local path, for working directory use $(pwd):/path/container - On windows may not work unless you are in your users folder
