How to resolve /dev/vda1 using 100% of disk space error

This problem is common when you are using docker to deploy application on serve. Every time a new docker image is pushed on server it occupies some memory and over the time it occupies a significant amount of disk space on server. to resolve this issue you can either run the following command manually

sudo docker system prune -a -f

or you can use the following script and set a cronjob to run it after a desired time of your choice:

#!/bin/bash
TIMESTAMP=$(date +"%d-%m-%Y_%H-%M-%S")
LOG_DIR="$HOME/docker-logs"
LOG_FILE="$LOG_DIR/$TIMESTAMP.log"
mkdir -p "$LOG_DIR"
echo "before pruning:" >> "$LOG_FILE"
df -h | sed -n '4p' >> "$LOG_FILE" 2>&1
echo "Running system prune at $TIMESTAMP" >> "$LOG_FILE"
sudo docker system prune -a -f >> "$LOG_FILE" 2>&1
echo "Completed system prune at $(date +"%d-%m-%Y_%H-%M-%S")" >> "$LOG_FILE"
echo "after  pruning:" >> "$LOG_FILE"
df -h | sed -n '4p' >> "$LOG_FILE" 2>&1

Here is another version of script it will show a loader while the script is running in background:

#!/bin/bash
animate() {
	local pid=$1
	local delay=0.1
	local spin='-\|/'
	local processing_text=$2
	while ps a | awk '{print $1}' | grep -q "$pid"; do
		printf '%s %c\r' "$processing_text" "$spin"
		spin=${spin#?}${spin%???}
		sleep "$delay"
	done
	printf '\r%s\n' "$processing_text" # Print the processing text on a new line
}

TIMESTAMP=$(date +"%d-%m-%Y_%H-%M-%S")
LOG_DIR="$HOME/docker-logs"
LOG_FILE="$LOG_DIR/$TIMESTAMP.log"
mkdir -p "$LOG_DIR"

# Start loading animation in the background
animate $$ "Processing..." &

# Store the PID of the animation process
animate_pid=$!

# Execute the script commands
{
	echo "before pruning:"
	df -h | sed -n '4p' >>"$LOG_FILE" 2>&1
	echo "Running system prune at $TIMESTAMP"
	sudo docker system prune -a -f
	echo "Completed system prune at $(date +"%d-%m-%Y_%H-%M-%S")"
	echo "after pruning:"
	df -h | sed -n '4p' >>"$LOG_FILE" 2>&1
} >>"$LOG_FILE" 2>&1

# Terminate the animation process
kill "$animate_pid" &>/dev/null
sleep 1.2
# Print success message on a new line
echo "\nSuccess!!"
