 Building and Running Docker Images 

Needs Base Image 
Dependencies 
Start-Up Command 


Touch Dockerfile (no file ext) 

inside of file with no ext. define system and variables 

# use an existing Image as base 
    FROM alpine
# download and install dep 
    RUN apk add --update redis
#the the image what to do

CMD ["redis-server"]


Then Go to Terminal and run docker build . (. meaning all files in folder) 
Will output ID of Build 

Then Docker Run (ID) 

instead of using ID everytime you can use convention to make custom file name 

-t yourDockerID/RepoName:version 

ex. joshuaaguilar20/DockerClass:1.0 . (last dot for all files) 
//builds repo
sudo docker build -t joshuaaguilar20/redisrepo:1.0  .

//runs repo
sudo docker run joshuaaguilar20/redisrepo:1.0



Basic Node DockerFile 

# use an existing Image as base Alpine means stripped down version
    FROM node:-alpine
# download and install dep 
   COPY ./ ./
    RUN npm install
      
#the the image what to do

CMD ["npm", "start"]

./ takes current working directory and copies it to current working dir of container



Build File Docker run build . (optional Name) 

docker run (filename or ID)
