# Slurm in Docker
**WORK IN PROGRESS**
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.
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
## Contents
1. [packages](packages) - Build the RPM packages for running Slurm and OpenMPI on CentOS 7
2. [base](base) - Slurm base image from which other components are derived
3. [controller](controller) - Slurm controller (head-node) definition
4. [database](database) - Slurm database definition (not necessary, but useful for accounting information)
5. [worker](worker) - Slurm worker (compute-node) definition
## Container Overview
An example [docker-compose.yml](docker-compose.yml) file is provided that builds and deploys the diagramed topology
<img width="90%" alt="Slurm cluster" src="https://user-images.githubusercontent.com/5332509/38642211-67a7e1a4-3da7-11e8-85a9-3394ad3c8cb6.png">
Listing of participating containers with FQDNs and their function within the cluster.
Container | Function | FQDN
:-------- | :------- | :---
controller | Slurm Primary Controller | controller.local.dev
database | Slurm Primary Database Daemon | database.local.dev
worker01 | Slurm Worker | worker01.local.dev
worker02 | Slurm Worker | worker02.local.dev
## Configure slurm.conf/slurmdbd.conf
Users may use the default slurm.conf file generated in [docker-entrypoint.sh](https://github.com/SciDAS/slurm-in-docker/blob/master/controller/docker-entrypoint.sh), or preferably create one to better fit their system.
The [Slurm Configuration Tool](https://slurm.schedmd.com/configurator.html) is a useful resource for creating custom slurm.conf files.
Steps to add user profided slurm.conf/slurmdbd.conf:
1. Create ```home/config``` and ```secret``` directories:
```
mkdir -p home/config secret
```
2. Copy configuration files to the ```home/config``` directory:
```
cp <user-provided-slurm.conf> home/config/slurm.conf; cp <user-provided-slurmdbd.conf> home/config/slurmdbd.conf
```
The user can then proceed as normal.
TODO: Have software check validity of custom configuration files.
## 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 .
```
Build the base image
```
docker build -t scidas/slurm.base:19.05.1 .
```
Verify image build
```console
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
scidas/slurm.base 19.05.1 1600621cb483 Less than a second ago 819MB
...
```
All images defined in `docker-compose.yml` will be built from the `scidas/slurm.base:19.05.1` base image
## Usage
An example [docker-compose.yml](docker-compose.yml) file is provided that builds and deploys the diagramed topology (`-d` is used to daemonize the call).
```
docker-compose up -d
```
Four containers should be observed running when completed
```console
$ docker ps

## Examples using Slurm
The examples make use of the following commands.
- `sinfo` - [man page](https://slurm.schedmd.com/sinfo.html)
- `sacctmgr` - [man page](https://slurm.schedmd.com/sacctmgr.html)
- `sacct` - [man page](https://slurm.schedmd.com/sacct.html)
- `srun` - [man page](https://slurm.schedmd.com/srun.html)
- `sbatch` - [man page](https://slurm.schedmd.com/sbatch.html)
- `squeue` - [man page](https://slurm.schedmd.com/squeue.html)
### controller
Use the `docker exec` call to gain a shell on the `controller` container.
```console
$ docker exec -ti controller /bin/bash
[root@controller /]#
```
Issue an `sinfo` call
```console
# sinfo -lN
Wed Apr 11 21:15:35 2018
NODELIST NODES PARTITION STATE CPUS S:C:T MEMORY TMP_DISK WEIGHT AVAIL_FE REASON
worker01 1 docker* idle 1 1:1:1 1998 0 1 (null) none
worker02 1 docker* idle 1 1:1:1 1998 0 1 (null) none
```
Create a `worker` account and `worker` user in Slurm
```console
# sacctmgr -i add account worker description="worker account" Organization=Slurm-in-Docker
Adding Account(s)
worker
Settings
Description = worker account
Organization = slurm-in-docker
Associations

# sacctmgr -i create user worker account=worker adminlevel=None
Adding User(s)
worker
Settings =
Admin Level = None
Associations =
U = worker A = worker C = snowflake
Non Default Settings
```
### database
Use the `docker exec` call to gain a MariaDB/MySQL shell on the `database` container.
```console
$ docker exec -ti database mysql -uslurm -ppassword -hdatabase.local.dev
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 9

+---------------+------------+---------+--------+-------------+
2 rows in set (0.00 sec)
```
### worker01 and worker02
Use the `docker exec` call to gain a shell on either the `worker01` or `worker02` container and become the user `worker`.
```console
$ docker exec -ti -u worker worker01 /bin/bash
[worker@worker01 /]$ cd ~
[worker@worker01 ~]$ pwd
/home/worker
```
Test password-less `ssh` between containers
```console
[worker@worker01 ~]$ hostname
worker01.local.dev
[worker@worker01 ~]$ ssh worker02
[worker@worker02 ~]$ hostname
worker02.local.dev
[worker@worker02 ~]$ ssh controller
[worker@controller ~]$ hostname
controller.local.dev
```
### Slurm commands
All commands are issued as the user `worker` from the `controller` node
```console
$ docker exec -ti -u worker controller /bin/bash
[worker@controller /]$ cd ~
[worker@controller ~]$ pwd
/home/worker
```
- For the rest of this section the `[worker@controller ~]$` prompt will be shortend to simply `$`
Test the `sacct` and `srun` calls
```console
$ sacct
JobID JobName Partition Account AllocCPUS State ExitCode
------------ ---------- ---------- ---------- ---------- ---------- --------
$ srun -N 2 hostname
worker01.local.dev
worker02.local.dev
$ sacct
JobID JobName Partition Account AllocCPUS State ExitCode
------------ ---------- ---------- ---------- ---------- ---------- --------
2 hostname docker worker 2 COMPLETED 0:0
```
Test the `sbatch` call
Make a job file named: `slurm_test.job`
```bash
#!/bin/bash
#SBATCH --job-name=SLURM_TEST
#SBATCH --output=SLURM_TEST.out
#SBATCH --error=SLURM_TEST.err
#SBATCH --partition=docker
srun hostname | sort
```
Run the job using `sbatch`
```console
$ sbatch -N 2 slurm_test.job
Submitted batch job 3
```
Check the `sacct` output
```console
$ sacct
JobID JobName Partition Account AllocCPUS State ExitCode
------------ ---------- ---------- ---------- ---------- ---------- --------
2 hostname docker worker 2 COMPLETED 0:0
3 SLURM_TEST docker worker 2 COMPLETED 0:0
3.batch batch worker 1 COMPLETED 0:0
3.0 hostname worker 2 COMPLETED 0:0
```
Check the output files
```console
$ ls -1
SLURM_TEST.err
SLURM_TEST.out
slurm_test.job
$ cat SLURM_TEST.out
worker01.local.dev
worker02.local.dev
```
Test the `sbatch --array` and `squeue` calls
Make a job file named `array_test.job`:
```bash
#!/bin/bash
#SBATCH -N 1
#SBATCH -c 1
#SBATCH -t 24:00:00
###################
## %A == SLURM_ARRAY_JOB_ID
## %a == SLURM_ARRAY_TASK_ID (or index)
## %N == SLURMD_NODENAME (directories made ahead of time)
#SBATCH -o %N/%A_%a_out.txt
#SBATCH -e %N/%A_%a_err.txt
snooze=$(( ( RANDOM % 10 ) + 1 ))
echo "$(hostname) is snoozing for ${snooze} seconds..."
sleep $snooze
```
This job defines output directories as being `%N` which reflect the `SLURMD_NODENAME` variable. The output directories will need to exist ahead of time in this particular case, and can be determined by finding all available nodes in the `NODELIST` and creating the directories.
```console
$ sinfo -N
NODELIST NODES PARTITION STATE
worker01 1 docker* idle
worker02 1 docker* idle
$ mkdir worker01 worker02
```
The job when run will direct it's output files to the directory defined by the node on which it is running. Each iteration will sleep from 1 to 10 seconds randomly before moving onto the next run in the array.
We will run an array of 20 jobs, 2 at a time, until the array is completed. The status can be found using the `squeue` command.
```console
$ sbatch --array=1-20%2 array_test.job
Submitted batch job 4
$ squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
4_[3-20%2] docker array_te worker PD 0:00 1 (JobArrayTaskLimit)
4_1 docker array_te worker R 0:01 1 worker01
4_2 docker array_te worker R 0:01 1 worker02
...
$ squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
4_[20%2] docker array_te worker PD 0:00 1 (JobArrayTaskLimit)
4_19 docker array_te worker R 0:04 1 worker02
4_18 docker array_te worker R 0:10 1 worker01
$ squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
```
Looking into each of the `worker01` and `worker02` directories we can see which jobs were run on each node.
```console
$ ls
SLURM_TEST.err array_test.job worker01
SLURM_TEST.out slurm_test.job worker02
$ ls worker01
4_11_err.txt 4_16_err.txt 4_1_err.txt 4_3_err.txt 4_7_err.txt
4_11_out.txt 4_16_out.txt 4_1_out.txt 4_3_out.txt 4_7_out.txt
4_14_err.txt 4_18_err.txt 4_20_err.txt 4_5_err.txt 4_9_err.txt
4_14_out.txt 4_18_out.txt 4_20_out.txt 4_5_out.txt 4_9_out.txt
$ ls worker02
4_10_err.txt 4_13_err.txt 4_17_err.txt 4_2_err.txt 4_6_err.txt
4_10_out.txt 4_13_out.txt 4_17_out.txt 4_2_out.txt 4_6_out.txt
4_12_err.txt 4_15_err.txt 4_19_err.txt 4_4_err.txt 4_8_err.txt
4_12_out.txt 4_15_out.txt 4_19_out.txt 4_4_out.txt 4_8_out.txt
```
And looking at each `*_out.txt` file view the output
```console
$ cat worker01/4_14_out.txt
worker01.local.dev is snoozing for 10 seconds...
$ cat worker02/4_6_out.txt
worker02.local.dev is snoozing for 7 seconds...
```
Using the `sacct` call we can see when each job in the array was executed
```console
$ sacct
JobID JobName Partition Account AllocCPUS State ExitCode

Create a file named `mpi_batch.job` in `/home/worker` (similar to the script used for the `sbatch --array` example from above, and make an output directory named `mpi_out`)
file `mpi_batch.job`:
```bash
#!/bin/bash

#SBATCH -c 1
#SBATCH -t 24:00:00
###################
## %A == SLURM_ARRAY_JOB_ID

#SBATCH -o mpi_out/%A_%a_out.txt
#SBATCH -e mpi_out/%A_%a_err.txt
snooze=$(( ( RANDOM % 10 ) + 1 ))
sleep $snooze
srun -N 2 --mpi=openmpi mpi_hello.out
```
Make directory `mpi_out`
```console
$ mkdir mpi_out

## Tear down
The containers, networks, and volumes associated with the cluster can be torn down by simply running:
```
./teardown.sh
```
Each step of this teardown may also be run individually:
The containers can be stopped and removed using `docker-compose`
```console
$ docker-compose stop
Stopping worker01 ... done
Stopping database ... done
Stopping worker02 ... done
Stopping controller ... done
$ docker-compose rm -f
Going to remove worker01, database, worker02, controller
Removing worker01 ... done
Removing database ... done
Removing worker02 ... done
Removing controller ... done
```
The network and volumes can be removed using their representative `docker` commands
- Volumes
```console
$ docker volume list
DRIVER VOLUME NAME
...
local slurmindocker_home
local slurmindocker_secret
$ docker volume rm slurmindocker_home slurmindocker_secret
slurmindocker_home
slurmindocker_secret
```
- Network
```console
$ docker network list
NETWORK ID NAME DRIVER SCOPE
...
a94c168fb653 slurmindocker_slurm bridge local
$ docker network rm slurmindocker_slurm
slurmindocker_slurm
```
## References
Slurm workload manager: [https://www.schedmd.com/index.php](https://www.schedmd.com/index.php)
- Slurm is a highly configurable open-source workload manager. In its simplest configuration, it can be installed and configured in a few minutes (see [Caos NSA and Perceus: All-in-one Cluster Software Stack](http://www.linux-mag.com/id/7239/1/) by Jeffrey B. Layton). Use of optional plugins provides the functionality needed to satisfy the needs of demanding HPC centers. More complex configurations rely upon a database for archiving accounting records, managing resource limits by user or bank account, and supporting sophisticated scheduling algorithms.
Docker: [https://www.docker.com](https://www.docker.com)
- Docker is the company driving the container movement and the only container platform provider to address every application across the hybrid cloud. Today’s businesses are under pressure to digitally transform but are constrained by existing applications and infrastructure while rationalizing an increasingly diverse portfolio of clouds, datacenters and application architectures. Docker enables true independence between applications and infrastructure and developers and IT ops to unlock their potential and creates a model for better collaboration and innovation.
OpenMPI: [https://www.open-mpi.org](https://www.open-mpi.org)
- The Open MPI Project is an open source [Message Passing Interface](http://www.mpi-forum.org/) implementation that is developed and maintained by a consortium of academic, research, and industry partners. Open MPI is therefore able to combine the expertise, technologies, and resources from all across the High Performance Computing community in order to build the best MPI library available. Open MPI offers advantages for system and software vendors, application developers and computer science researchers.
Lmod: [http://lmod.readthedocs.io/en/latest/index.html](http://lmod.readthedocs.io/en/latest/index.html)
- Lmod is a Lua based module system that easily handles the MODULEPATH Hierarchical problem. Environment Modules provide a convenient way to dynamically change the users’ environment through modulefiles. This includes easily adding or removing directories to the PATH environment variable. Modulefiles for Library packages provide environment variables that specify where the library and header files can be found.
