Docker postgres db to local volume/drive for persistent storage permanently

Hi all,

Today, I would be explaining the way to maintain the DB with data persistent when connecting to docker.

System Status

Postgresql DB container is in Docker
Windows 10 PC
Linux containers

Issue

Whenever I restart docker/PC the database wiped off due to container is stopped.

Solution

Create a docker volume

Syntax: docker volume create <>
Example: docker volume create pgdata

Start the container with volume option

Syntax: docker run --rm --name <> -e POSTGRES_PASSWORD=<> -d -p 5432:5432 -v <>:/var/lib/postgresql/data <>
Example: docker run --rm --name pgcontainer -e POSTGRES_PASSWORD=MyPassword -d -p 5432:5432 -v pgdata:/var/lib/postgresql/data postgres

Now, you can run all your database commands

Upon restart also, your data should be safe.

Thanks for reading the blog post.

Android insufficient permissions for device

Hi Friends,

I was having an issue when connected my friend's Micromax Doodle to my Ubuntu with the following error
"insufficient permissions for device"

Resolution

1. Open Terminal
2. Kill the server by typing the following command
• $ adb kill-server
3. Now, start the server
• $ adb start-server
4. On your device, a pop-up might come asking for granting the permission
5. Click on "Yes" for approving the access
6. Now, check your device status with the following command
• adb devices
7. With the above command, you should be able to see devive IMEI and device name

Enjoy the Ubuntu and Android combination :)
