Run a docker container:
export MY_IP=<my server IP>
sudo docker run -it --rm --cap-add=NET_ADMIN -p 1194:1194/udp -e HOST_ADDR=$MY_IP --name dockovpn alekslitvinenk/openvpn
Determined its IP address:
sudo docker ps
sudo docker inspect dockovpn | grep IPAddress
The binding did not work for me until I switched from Internal Virtual Switch to External Virtual Switch and while switching I were getting the following error:
[Window Title]
Virtual Switch Manager for MY-MACHINE
[Main Instruction]
Error applying Virtual Switch Properties changes
[Content]
Failed while adding virtual Ethernet switch connections.
[Expanded Information]
External Ethernet adapter 'Realtek PCIe GBE Family Controller' is already bound to the Microsoft Virtual Switch protocol.
until I switched Hyper-V Extensible Virtual Switch off on my network adapter properties page (after I created External Virtual Switch it switched on back):

git clone https://github.com/oracle/docker-images
Install docker, download Oracle Database, put it to the directory docker-images/OracleDatabase/SingleInstance/dockerfiles/18.3.0 containing the Dockerfile and run the following commands to build and run Enterprise Edition:
cd docker-images/OracleDatabase/SingleInstance/dockerfiles/18.3.0
mv ~/Downloads/LINUX.X64_180000_db_home.zip .
# Fix a small bug in Dockerfile, see https://github.com/oracle/docker-images/issues/1468
sed -i 's/V981623-01/LINUX.X64_180000_db_home/g' Dockerfile
sudo docker build -t oracle/database:18.3.0 --build-arg DB_EDITION=EE .
sudo docker run -d -it --rm --name oracle18 oracle/database:18.3.0
sudo docker logs oracle18 --tail 100
sudo docker logs oracle18 | grep -i password
and the following commands to build and run Standard Edition 2 (it does not require V981623-01.zip):
sudo docker build -t oracle/database-se:18.3.0 --build-arg DB_EDITION=SE2 .
sudo docker run -d -it --rm --name oracle18se oracle/database-se:18.3.0
sudo docker logs oracle18se --tail 100
the first string of the docker output contains the generated password for SYS, SYSTEM and PDBADMIN.

cat /proc/cpuinfo dpkg --print-architecture
After I installed Docker, I successfully run its test application:
docker run hello-world
Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world b04784fba78d: Pull complete Digest: sha256:f3b3b28a45160805bb16542c9531888519430e9e6d6ffc09d72261b0d26ff74f Status: Downloaded newer image for hello-world:latest Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
