Docker

fast, easy and portable application development through containerization

If I haven't figured out a way to containerize) an app, I will find a way. Pretty much the backbone of how I deploy and maintain many services.

connections

installation

  1. Install Docker Desktop on Linux

Tips & Tricks

specifiy a file other than docker-compose.yml or compose.yml

docker-compose -f docker-compose.test.yml up

execute a command

sudo docker exec -it dev-garden-app-1 ls /public # '/public = whatever directory you want to look into'

sudo docker exec -it dev-garden-app-1 /bin/bash # 'heard you like shell inside your shell'

Map Volume on Windows 10

1.  Launch Docker from your windows taskbar
2.  Click on Settings icon on top
3.  Click Resources
4.  Click File Sharing
5.  Click on (+) sign and add path of local folder in which you want to map the container volume.

It worked for me.

"C:\\ProgramData\\Docker\\volumes\\sqldata:c:\\mssql"

macOS app not responding upon launch

  1. Go to finder and open Applications > Utilities > Activity Monitor.app

  2. Find Docker or Docker Desktop (it was in Not responding mode in my case) and Force Kill the app.

  3. Run the following command in Terminal:

    sudo rm -rf ~/Library/Containers/com.docker.*

  4. Open the setting file in the terminal:

    sudo nano ~/Library/Group\ Containers/group.com.docker/settings.json

then find "filesharingDirectories":

  1. Remove all entries inside this key and leave it as "filesharingDirectories": [], save and close the file.
  2. Finally go to the Application folder, find Docker and run it (wait sometime, it takes a minute or so to run)
  3. It will run and work like a charm!

Run Docker Compose in Crontab

running docker compose up -d is the norm when you're already in the same directory as the compose.yml file, but what if you want to call that same file from a crontab

# spin up container from selected file
docker compose -f /home/mypath/compose.yml up -d 
docker compose -f /mnt/uasis5/node/filesystem-livesync-pywriter4/compose.yml up -d

# restart container 'server' named in compose.yml file
docker compose -f /mnt/uasis5/node/filesystem-livesync-pywriter4/compose.yml restart server

#todo
