[SOLVED]Docker API connection refused 127.0.0.1:2376

Create a file called /etc/systemd/system/docker-tcp.socket to make Docker available on a TCP socket on port 2375.

[Unit]
Description=Docker Socket for the API

[Socket]
ListenStream=2375
BindIPv6Only=both
Service=docker.service

[Install]
WantedBy=sockets.target


Then enable this new socket:

systemctl enable docker-tcp.socket
systemctl stop docker
systemctl start docker-tcp.socket
systemctl start docker
Test that it's working:

docker -H tcp://127.0.0.1:2375 ps

[SOLVED] Create copy of Raspberry PI SD-Card


sudo fdisk -l

Take note of how the SD card is identified.
In my case it is /dev/sdb1.
Then:
sudo dd bs=4M if=/dev/sdb | gzip > /home/your_username/image`date +%d%m%y`.gz

This will compress the image using gzip.
To restore the backup on SD card:
sudo gzip -dc /home/your_username/image.gz | sudo dd bs=4M of=/dev/sdb
