dev-env

The repository contains files for managing a virtualized development environment.

Entering the development environment (DE) is possible from any directory on the host machine with dev-env command, after which the host current directory is mounted in the DE as the workspace folder.

Pros

• Does not require installing hundreds of packages on the host machine
• All packages in the DE stay up-to-date without any effort to update
• Fault tolerant environment (any changes to system directories or packages in the DE are discarded at the end of the session)
• Package conflicts and installation issues are very unlikely considering all packages installed in the DE are always up-to-date. On top of that any changes to the system directories are always discarded at the end of each session preventing any potential errors made to the packages

Cons

• Not everybody is a fan of terminal and doing ther development within it
• Requires 950 MB of HDD space for virtual image to be built
• Rebuilding may vary from seconds up to 10 minutes depending on the change in packages (order in specific) as well as internet speed to fetch the packages

Example

user ~ $ cd ~/helloworld
user ~/helloworld $ which binwalk
binwalk not found
user ~/helloworld $ dev-env
env0 /workspace/helloworld $ binwalk file

Optional arguments

With no flags, dev-env will mount the host current directory with read-write mode, any modification to the files will affect the host machine.

Read-only flag (dev-env -r) mounts the host current directory as read-only within the DE.

Read-only + mutable flag (dev-env -rm) copies the current host directory to a temporary location and mounts it in the DE. The directory is then automatically deleted at the end of the session, therefore no changes are done to the host files.

Optional flag to use no network (dev-env -n) guarantees no data via network can get out from the container

Optional env variables

Run any image (i.e. an older i386 ubuntu) by providing IMAGE in the environment variables:

IMAGE=ioft/i386-ubuntu:14.04.3 dev-env
