ubuntu - Docker: Is it necessary to mount a new partition -
i want install product on docker. installed on ec2-server of amazon.
the installation starts creating mount point /product
. partition disk fdisk
, they're creating new partition. after create filesystem , mount new partition /product
.
i'm not familiar seems me main goal install product on 1 new disk.
the installation performed on ubuntu:14.04
want start this:
docker run -i -t ubuntu:14.04 /bin/bash
performing same installation instructions , create image of container.
is necessary perform of mount instructions or can start installation?
perform of mount instructions
not exactly.
best practice define installation step in dockerfile
, starting from ubuntu:14.04
, , including volume /mount
in order declare /mount
volume.
this preferred docker run
+ (work) + (exit) + docker commit
, because dockerfile, can repeat installation process simple docker build
. , keep specification of installation written in dockerfile.
the alternative go way, , try extract dockerfile resulting image.
in case, docker commit
allows apply dockerfile instruction image created.
typically, mount done @ time:
docker commit -c='volume /mount'` <yourcontainer> <yourimage>`
