+
+[Introduction]
+The Docker daemon can listen to Docker Remote API requests via three types of
+Socket: unix, tcp and fd. By default, a unix domain socket (or IPC socket) is
+created at /var/run/docker.sock, requiring either root permission, or docker
+group membership.
+
+Port 2375 is conventionally used for un-encrypted communition with Docker daemon
+remotely, where docker server can be accessed by any docker client via tcp socket
+in local area network. You can listen to port 2375 on all network interfaces with
+-H tcp://0.0.0.0:2375, where 0.0.0.0 means any available IP address on host, and
+tcp://0.0.0.0:2375 indicates that port 2375 is listened on any IP of daemon host.
+If we want to make docker server open on the Internet via TCP port, and only trusted
+clients have the right to access the docker server in a safe manner, port 2376 for
+encrypted communication with the daemon should be listened. It can be achieved to
+create certificate and distribute it to the trusted clients.
+
+Through creating self-signed certificate, and using --tlsverify command when running
+Docker daemon, Docker daemon opens the TLS authentication. Thus only the clients
+with related private key files can have access to the Docker daemon's server. As
+long as the key files for encryption are secure between docker server and client,
+the Docker daemon can keep secure.
+In summary,
+Firstly we should create docker server certificate and related key files, which
+are distributed to the trusted clients.
+Then the clients with related key files can access docker server.
+
+[Steps]
+1.0. Create a CA, server and client keys with OpenSSL.
+ OpenSSL is used to generate certificate, and can be installed as follows.
+ apt-get install openssl openssl-devel
+
+1.1 First generate CA private and public keys.
+ openssl genrsa -aes256 -out ca-key.pem 4096
+ openssl req -new -x509 -days 365 -key ca-key.pem -sha256 -out ca.pem
+
+ You are about to be asked to enter information that will be incorporated
+ into your certificate request, where the instance of $HOST should be replaced
+ with the DNS name of your Docker daemon's host, here the DNS name of my Docker
+ daemon is ly.
+ Common Name (e.g. server FQDN or YOUR name) []:$HOST
+
+1.2 Now we have a CA (ca-key.pem and ca.pem), you can create a server key and
+certificate signing request.
+ openssl genrsa -out server-key.pem 4096
+ openssl req -subj "/CN=$HOST" -sha256 -new -key server-key.pem -out server.csr
+
+1.3 Sign the public key with our CA.
+ TLS connections can be made via IP address as well as DNS name, they need to be
+ specified when creating the certificate.
+
+ echo subjectAltName = IP:172.16.10.121,IP:127.0.0.1 > extfile.cnf
+ openssl x509 -req -days 365 -sha256 -in server.csr -CA ca.pem -CAkey ca-key.pem \
+ -CAcreateserial -out server-cert.pem -extfile extfile.cnf
+
+1.4 For client authentication, create a client key and certificate signing request.
+ openssl genrsa -out key.pem 4096
+ openssl req -subj '/CN=client' -new -key key.pem -out client.csr
+
+1.5 To make the key suitable for client authentication, create an extensions config file.
+ echo extendedKeyUsage = clientAuth > extfile.cnf
+
+1.6 Sign the public key and after generating cert.pem and server-cert.pem, two certificate
+ signing requests can be removed.
+ openssl x509 -req -days 365 -sha256 -in client.csr -CA ca.pem -CAkey ca-key.pem \
+ -CAcreateserial -out cert.pem -extfile extfile.cnf
+
+1.7 In order to protect your keys from accidental damage, you may change file modes to
+ be only readable.
+ chmod -v 0400 ca-key.pem key.pem server-key.pem
+ chmod -v 0444 ca.pem server-cert.pem cert.pem
+
+1.8 Build docker server
+ dockerd --tlsverify --tlscacert=ca.pem --tlscert=server-cert.pem --tlskey=server-key.pem \
+ -H=0.0.0.0:2376
+ Then, it can be seen from the command 'netstat -ntlp' that port 2376 has been listened
+ and the Docker daemon only accept connections from clients providing a certificate
+ trusted by our CA.
+
+1.9 Distribute the keys to the client
+ scp /etc/docker/ca.pem wwl@172.16.10.121:/etc/docker
+ scp /etc/docker/cert.pem wwl@172.16.10.121:/etc/docker
+ scp /etc/docker/key.pem wwl@172.16.10.121:/etc/docker
+ Where, wwl and 172.16.10.121 is the username and IP of the client respectively.
+ And the password of the client is needed when you distribute the keys to the client.
+
+1.10 To access Docker daemon from the client via keys.
+ docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem \
+ -H=$HOST:2376 version
+
+ Then we can operate docker in the Docker daemon from the client vis keys, for example:
+ 1) create container from the client
+ docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=ly:2376 run -d \
+ -it --name w1 grafana/grafana
+ 2) list containers from the client
+ docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=ly:2376 pa -a
+ 3) stop/start containers from the client
+ docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=ly:2376 stop w1
+ docker --tlsverify --tlscacert=ca.pem --tlscert=cert.pem --tlskey=key.pem -H=ly:2376 start w1
+
+
