Use [Docker](https://www.docker.com/) to explore the various components of [Slurm](https://www.schedmd.com/index.php)
This work represents a small exploratory Slurm cluster using CentOS 7 based Docker images. The intent was to learn the basics of Slurm prior to extending the concept to a more distributed environment.
This work represents a small exploratory Slurm cluster using AlmaLinux 9 based Docker images.
Images include:
- [Slurm 19.05.1](https://slurm.schedmd.com) - installed from [rpm packages](packages)
- [OpenMPI 3.0.1](https://www.open-mpi.org/doc/current/) - installed from [rpm packages](packages)
- [Lmod 7.7](http://lmod.readthedocs.io/en/latest/index.html) - installed from [distribution files](https://sourceforge.net/projects/lmod/files/)
- [Lmod module packages for CentOS 7](https://github.com/scidas/lmod-modules-centos) - Organized for Slurm-in-Docker use
- [Using Lmod with Slurm-in-Docker](using-lmod-with-slurm-in-docker.md) documentation
- [Slurm 24.05.3](https://slurm.schedmd.com) - built from source RPMs inside the container

## Build
Build the slurm RPM files by following the instructions in the [packages](packages) directory.
**Create the base Slurm image**:
Copy the `packages/centos-7/rpms` directory to the `base` directory
```
cd base/
cp -r ../packages/centos-7/rpms .
make
```
Build the base image
```
docker build -t scidas/slurm.base:19.05.1 .
```
This builds `clustercockpit/slurm.base:24.05.3` from AlmaLinux 9, compiling Slurm RPMs from source with JWT and slurmrestd support.
Verify image build
