How to mount a host directory in a Docker Container
Author: Venkata Sudhakar
Docker is an open platform to develop, ship, and run containerized applications.
It separates infra from application to ease application development and support anywhere development strategy. The below example shows how to mount a host directory in a Docker Container. Place couple of files under C:/VENKAT directory on Host and map it to /usr/share/nginx/html inside the container in readonly mode (ro).
01 | C:\>docker run -v C:/VENKAT:/usr/share/nginx/html:ro -p 9090:80 -d nginx |
02 | d50f1723a2c9c83417d9ceac701c54ca5e6e4858395ffff72293b4a54c95ce7f |
04 | Connect to the container and verify if you can access files from the mouted volume. |
05 | C:\>docker exec -it 171dd986eeb3 bash |
06 | root@171dd986eeb3:/# cd /usr/share/nginx/ |
07 | root@171dd986eeb3:/usr/share/nginx/html# cat index.html |
08 | <h1>Hello World from Host Local Directory</h1> |
09 | root@171dd986eeb3:/usr/share/nginx/html# |
11 | Once nginx server starts, we can access all files under C:/VENKAT directory over HTTP. |
