Now you can run `./project make` in the initial container. You will see -that all the built products (temporary or final datasets or PDFs), will be -written in the `/PATH/TO/PROJECT/ANALYSIS/OUTPUTS` directory of your -host. You can even change the source of your project on your host operating -system an re-run Make to see the effect on the outputs and add/commit the -changes to your Git history within your host. You can also exit the -container any time. You can later load the `PROJECT-ENV` environment image -into a new container with the same `docker run -v ...` command above, just -use `PROJECT-ENV` instead of `PROJECT`. + 7. Make the `docker-run` script executable and **put its name in your + `.gitignore`**. It is important that this file doesn't go into your + project's history because it contains directory names only for this + particular system (you can always recreate it and update the directory + values for another system, by looking at this `README.md` and + copy-pasting). If you use the standard `docker-run` name for this tiny + script, it is already included in Maneage's `.gitignore`, so you don't + need to re-insert it there. -8. In case you want to store the image as a single file as backup or to -move to another computer, you can run the commands below. They will produce -a single `project-env.tar.gz` file. + ```shell + chmod docker-run + emacs .gitignore + ``` -```shell -docker save -o project-env.tar PROJECT-ENV -gzip --best project-env.tar -``` + 8. You can now start the Docker image by executing your newly added + script like below (it will ask for your root password). You will + notice that you are in the Docker container with the changed prompt. + + ```shell + ./docker-run + ``` + + 9. You are now within the container. Go into the project source directory + and run these commands to build the software environment. + + ```shell + cd source + ./project configure --build-dir=/home/maneager/build \ + --software-dir=/home/maneager/software \ + --input-dir=/home/maneager/data + ``` + + 10. After the configuration finishes successfully, it will say so. It will + then ask you to run `./project make`. **But don't do that yet**.

Open a new terminal, and follow the steps described in the + sub-section above to preserve (or "commit") the built container as a + Docker image. Let's assume you call it `MY-PROJECT-ENV`. After the new + image is made, you should be able to see the new image in the list of + images with this command (in yet another terminal): + + ```shell + docker image list # In the other terminal. + ``` + + 11. Now that you have safely "committed" your current Docker container + into a separate Docker image, you can **exit the container** safely + with the `exit` command. Don't worry, you won't loose the built + software environment: it is all now saved separately within the Docker + image. + + 12. Re-open your `docker-run` script and change `MANEAGEBASE` to + `MY-PROJECT-ENV` (or any other name you set for the environment you + committed above). + + ```shell + emacs docker-run + ``` + + 13. That is it! You can now always easily enter your container (only for + the software environemnt) with the command below. Within the + container, any file you save/edit in the `source` directory of the + docker container is the same file on your host OS and any file you + build in your `build/analysis` directory (within the Maneage'd + project) will be on your host OS. You can even use your container's + Git to store the history of your project in your host OS. See the next + step in case you want to move your built software environment to + another computer. + + ```shell + ./docker-run + ``` + + 14. In case you want to store the image as a single file as backup or to + move to another computer, you can run the commands below. They will + produce a single `project-env.tar.gz` file. + + ```shell + docker save -o my-project-env.tar MY-PROJECT-ENV + gzip --best project-env.tar + ``` + + 15. To load the tarball above into a clean docker environment (for example + on another system) copy the `my-project-env.tar.gz` file there and run + the command below. You can then create the `docker-run` script for + that system and run it to enter. Just don't forget that if your + `analysis_dir` directory is empty on the new/clean system. So you + should first run the same `./project configure ...` command above in + the docker image so it connects the environment to your source. Don't + worry, it won't build any software and should finish in a second or + two. Afterwards, you can safely run `./project make` and continue + working like you did on the old system. + + ```shell + docker load --input my-project-env.tar.gz + ``` -9. To load the tarball above into a clean docker environment (either on the -same system or in another system), and create a new container from the -image like above (the `docker run -v ...` command). Just don't forget that -if your `/PATH/TO/PROJECT/ANALYSIS/OUTPUTS` directory is empty on the -new/clean system, you should first run `./project configure -e` in the -docker image so it builds the core file structure there. Don't worry, it -won't build any software and should finish in a second or two. Afterwards, -you can safely run `./project make`. -```shell -docker load --input project-env.tar.gz -``` |
