Docker

# Helpful Docker commands and code snippets
###############################################################################
### CONTAINERS ###
docker stop $(docker ps -a -q) #stop ALL containers
docker rm -f $(docker ps -a -q) # remove ALL containers
docker rm -f $(sudo docker ps --before="container_id_here" -q) # can also filter
# exec into container
docker exec -it $(docker container ls | grep '<seach_term>' | awk '{print $1}') sh
# exec into container on windows with Git Bash
winpty docker exec -it $(docker container ls | grep '<seach_term>' | awk '{print $1}') sh
# helps with error: 'unexpected end of JSON input'
docker rm -f $(docker ps -a -q) # Remove all in one command with --force
docker exec -i -t "container_name_here" /bin/bash # Go to container command line
# to exit above use 'ctrl p', 'ctrl q' (don't exit or it will be in exited state)
docker rm $(docker ps -q -f status=exited) # remove all exited containers
### IMAGES ###
# list images and containers
docker images | grep "search_term_here"
# remove image(s) (must remove associated containers first)
docker rmi -f image_id_here # remove image(s)
docker rmi -f $(docker images -q) # remove ALL images!!!
docker rmi -f $(docker images | grep "^<none>" | awk '{print $3}') # remove all <none> images
docker rmi -f $(docker images | grep 'search_term_here' | awk '{print $1}') # i.e. 2 days ago
docker rmi -f $(docker images | grep 'search_1\|search_2' | awk '{print $1}')
### DELETE BOTH IMAGES AND CONTAINERS ###
docker images && docker ps -a
# stop and remove containers and associated images with common grep search term
docker ps -a --no-trunc | grep "search_term_here" | awk "{print $1}" | xargs -r --no-run-if-empty docker stop && \
docker ps -a --no-trunc | grep "search_term_here" | awk "{print $1}" | xargs -r --no-run-if-empty docker rm && \
docker images --no-trunc | grep "search_term_here" | awk "{print $3}" | xargs -r --no-run-if-empty docker rmi
# stops only exited containers and delete only non-tagged images
docker ps --filter 'status=Exited' -a | xargs docker stop docker images --filter "dangling=true" -q | xargs docker rmi
### DELETE NETWORKS AND VOLUMES ###
# clean up orphaned volumes
docker volume rm $(docker volume ls -qf dangling=true)
# clean up orphaned networks
docker network rm $(docker network ls -q)
### NEW IMAGES/CONTAINERS ###
# create new docker container, ie. ubuntu
docker pull ubuntu:latest # 1x pull down image
docker run -i -t ubuntu /bin/bash # drops you into new container as root
### OTHER ###
# install docker first using directions for installing latest version
# https://docs.docker.com/installation/ubuntulinux/#ubuntu-trusty-1404-lts-64-bit
# other great tips: http://www.centurylinklabs.com/15-quick-docker-tips/

#### List all committed files being tracked by git
git ls-tree --full-tree -r HEAD
### Display remote origin ###
git remote --verbose
### Clone single branch from repo
git clone -b --single-branch <branch> <remote_repo>
### Get all branches from a repo
git branch -r | grep -v '\->' | while read remote; do git branch --track "${remote#origin/}" "$remote"; done
git fetch --all

git add -A && git commit -m "Removing cached files from GitHub" && git push
# works even better!
git rm --cached -r . && git add .

# Finding and tagging old commit points
git log --pretty=oneline # find hash of commit
git tag -a v0.1.0 -m 'version 0.1.0' <partial_commit_hash_here>
git push --tags #origin master
git tag # list all tags
git checkout tags/v0.1.0 # check out that tagged point in commit history
# Chaning a tag to a new commit
git push origin :refs/tags/<tagname>
git tag -fa <tagname>
git push origin master --tags
# Remove a tag both locally and remote
git tag -d <tagname>; # local
git push origin ::refs/tags/<tagname> # remote
### Committing changes to GitHub ###
git add -A # add all
git commit -m "my changes..."
git push
# Combined
git add . && git commit -am "Initial commit of project" && git push
### Adding an existing project to GitHub ###
# Create repo in GitHub first
git add -A # add all
git commit -m "Initial commit of project"
git remote add origin <https://github.com/username/repo.git>
git remote -v # verify new remote
git pull origin master # pull down license and .gitignore
# might get message like to merge manually: 'Error reading...Press Enter to continue starting nano.'
git push --set-upstream origin master
git status # check if add/commit/push required?
### Branching GitHub repos ###
# https://github.com/Kunena/Kunena-Forum/wiki/Create-a-new-branch-with-git-and-manage-branches
# Run from within local repo
NEW_BRANCH=<new_branch_here>
git checkout -b ${NEW_BRANCH}
git push origin ${NEW_BRANCH}
git branch # list branches
git add -A # add all
git commit -m "my changes..."
git push --set-upstream origin ${NEW_BRANCH}
git checkout master # switch back to master
# Merge in the <new_branch_here> branch to master
# https://www.atlassian.com/git/tutorials/using-branches/git-merge
git checkout master
git merge ${NEW_BRANCH}
# deletes branch!!
git branch -d ${NEW_BRANCH} # deletes branch!!
