following the freecodecamp git guide - a project to help learn how to use git and docker containers
- https://www.freecodecamp.org/news/what-is-git-and-how-to-use-it-c341b049ae61/
- https://towardsdatascience.com/getting-started-with-git-and-github-6fcd0f2d4ac6
- https://webkul.com/blog/syncing-local-repository-with-remote-repository-on-github/ !! for synching local repository with remote
-> cd c:\git\docker-node-quickstart !!navigate to local dir
-> git init !! adds a local git repository
-> git add . !! adds all files and folders in local folder to the staging area
-> git commit -m "initial commit for docker quickstart guide for nodejs project" !! committing all files and folders added
-> git status !! shows status regarding what files are modified and what files are in th staging area
-> git log !! show informaiton on commit
-> git branch test !! creates branch named test
-> git checkout test !! navigate to test branch
-> git branch !! list all branches
!!add and commit instructions when in test branch will add and commit to test branch
!!to merge, go back to master branch
-> git checkout master
-> git merge test !! merges test branch to master branch
create new repository in the github webpage
copy url or github repository
-> git remote add origin https://github.com/cheenkuan/docker-node-quickstart.git !! repository url
-> git push -u origin main !! pushes code from the master branch in the local repository to the master branch in the remote repository
!! git default uses main, not master; should push to main
-> git log !! shows the commits
-> git push -u origin --all !! use this push command for first time push
-> git remote -v !! show remote repositories
-> git pull origin master !! pulls the latest changes in the master branch in the remote repository to the local repository
-> git clone [repository url] !! clones an existing remote repository into local
-> git branch -m <oldname> <newname> !! change branch name
-> git branch -m <newname> !! if change name of current branch, then there is no need to specify old name
-> git branch -M <newname> !! if using case-sensitive file system and mane change is only for change in case, use -M
-> git branch <branch-name> --set-upstream-to=origin/<branch-name-in-remote> !! connecting/changing of local branch with remote branch
-> git branch --unset-upstream !! disconnecting link between local branch and remote branch
-> git branch -d <local_branch_name> !! delete local branch
-> git push origin --delete <remote_branch_name> !! delete remote branch
-> git pull origin master !! pulling changes from the remote repo, eg changes to Readme file
- https://github.com/cheenkuan/docker-node-quickstart.git
- https://docs.docker.com/get-started/nodejs/build-images/
-> cd docker-node-quickstart !! navigate to the project folder
-> npm init -y !! set up a npm package
-> npm install ronin-server ronin-mocks
- create new server.js file with following content
const ronin = require( 'ronin-server' )
const mocks = require( 'ronin-mocks' )
const server = ronin.server()
server.use( '/', mocks.server( server.Router(), false, true ) )
server.start()
- open terminal to run server.js
->node server.js
- test server.js using Postman
curl --location --request POST 'http://localhost:8000/test' \
--header 'Content-Type: application/json' \
--data-raw '[
{
"msg": "testing"
},
{
"code":"success","payload":[{"msg":"testing","id":"31f23305-f5d0-4b4f-a16f-6f4c8ec93cf1","createDate":"2020-08-28T21:53:07.157Z"}]
}
]'
curl --location --request GET 'http://localhost:8000/test' \
--header 'Content-Type: application/json' \
--data-raw '{
"code":"success","meta":{"total":1,"count":1},
"payload":[{"msg":"testing","id":"31f23305-f5d0-4b4f-a16f-6f4c8ec93cf1","createDate":"2020-08-28T21:53:07.157Z"}]
}'
- terminal will show server logs:
2020-XX-31T16:35:08:4260 INFO: POST /test 2020-XX-31T16:35:21:3560 INFO: GET /test
- create Dockerfile using visual studio with following content
FROM node:12.19.0 *!! creating the docker image from the official node image ver 12.19.0*
ENV NODE_ENV=production *!! specifies the environment in which application will be running; setting it to production environment improves performance*
WORKDIR /app *!! sets the working directory as /app, which will be the default directory for all subsequent commands*
COPY ["package.json", "package-lock.json*", "./"] *!! copies the packages into /app*
RUN npm install *!! install package.json, package-lock.json*
COPY . . *!! takes all files in the current directory and copies them to image*
CMD [ "node", "server.js" ] *!! tells docker the command to run when the image is run inside a container*
-> docker build --tag docker-node-quickstart . !! builds the docker image
-> docker run --publish 8000:8080 docker-node-quickstart !! starts the container and expose port 8000 to port 8000 on the host
-> docker run -d -p 8000:8000 docker-node-quickstart !! alternative to above to run the container in detached mode
-> docker --v !! shows docker version
-> docker images !! shows images
-> docker tag docker-node-quickstart:latest docker-node-quickstart:1.0.0 !! create new tag for image
-> docker rmi docker-node-quickstart:1.0.0 !! untag an image if there are more than 1 tag for 1 image
-> docker rmi docker-node-quickstart:latest !! delete an image if the image has only 1 tag
-> docker rmi -f docker-node-quickstart:latest !! sometimes it is necessary to force the deletion with -f
-> docker stop <name_of_container> !! stops a container
-> docker restart <name_of_container> !! restarts a stopped container
-> docker rm <name_of_container> !! removes a container; removed container will not remain resident in stopped state
-> docker ps -a or docker ps --all !! list all running docker containers
-> docker tag <IMAGE ID> cheenkuan/docker-node-quickstart:latest !! tagging image to Docker Hub remote repository
-> docker push cheenkuan/docker-node-quickstart:latest !! push image to Docker Hub remote repository
-> docker restart <container name> !! restart a stopped container
