The Nautilus DevOps team is testing applications containerization, which issupposed to be migrated on docker container-based environments soon. In today's stand-up meeting one of the team members has been assigned a task to create and test a docker container with certain requirements. Below are more details:
a. On App Server 3 in Stratos DC pull nginx image (preferably latest tag but others should work too).
b. Create a new container with name demo from the image you just pulled.
c. Map the host volume /opt/sysops with container volume /usr/src. There is an sample.txt file present on same server under /tmp; copy that file to /opt/sysops. Also please keep the container in running state.
Login to the App Server and switch to root. For the server credentials, check out the Project Nautilus documentation.

docker pull nginx:latest Copy the sample text file to the specified directory.
cp /tmp/sample.txt /opt/sysopssRun the container using the image and specify the name and volume mapping.
docker run --name demo -v /opt/sysopss:/usr/src/ -d -it nginx:latestCheck the container. Confirm that the mapping was successful.
