This project is an attempt to make certain commands easily available by using containers. It attempts to workaround any user/group and permissions mismatches and by providing the homedirectory and current working directory to the command being executed.
Add to a bourne compatible shells config (eg. $HOME/.bashrc) the following
line:
source /path/to/checkout/setup
Afterwards, open a fresh shell and the commands provided will be appended to
your shell's $PATH.
For every container there is a directory. Each directoy must contain a
Dockerfile that constructs the image used to perform the commands in. The
do executable can be used to run a command inside that container, which will
be executed with the same UID en GID as the user invoking it. The do command
will build the container image for that container, if it doesn't already exist.
It will also build a user specific image with the additional user information
added. Then it will start a one-shot container as the current user, forwarding
all relevant paths to the container and runs the indicated command with any
additional arguments provided.
Example:
./do postgres psql service=some-db
This will run the psql command, in the container using the image build from the postgres/Dockerfile, with service=some-db as command line argument.
Each directory should also contain a bin/ directory with symlinks for all the
commands we want to expose. These symlinks should all point to
../../argv0-stub, which is a helper script that will call the do command
for that command in that command's container.
