+# building a matlab R2022a toy system for singularity and docker image for CI
+
+Tru <tru@pasteur.fr>
+
+## Why ?
+- toy system for gitlab-CI
+- build docker image from dockerhub registry and push to registry.pasteur.fr with proper tags
+- build docker image, push to registry.pasteur.fr and re-use that docker image to create a singularity container as artefact
+- keeping an onsite version of https://hub.docker.com/r/mathworks/matlab
+
+## Caveat
+- playground, use at your own risk!
+- `:main` tagged docker image
+- `:latest` tagged singularity image
+
+## Usage:
+
+Docker: cf https://hub.docker.com/r/mathworks/matlab
+```
+docker run -e MLM_LICENSE_FILE=27000@MyLicenseServer -ti registry-gitlab.pasteur.fr/tru/singularity-docker-matlab-r2022a:main
+```
+Singularity:
+```
+singularity run  --env MLM_LICENSE_FILE=27000@MyLicenseServer oras://registry-gitlab.pasteur.fr/tru/singularity-docker-matlab-r2022a:latest
+```
