-Encrypt the docker remote API via TLS for Ubuntu and CentOS
-
-[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
