# Containers
[Docker](https://www.docker.com/) and [Singularity](https://sylabs.io/singularity/) recipes.
## Singularity
### Build
```bash
sudo singularity build .sif .def
```
or
```bash
sudo singularity build --notest .sif .def
```
The `--notest` flag is needed to prevent [Singularity](https://sylabs.io/singularity/) to run the tests, in case they need GPU support.
### Test
```bash
singularity test --nv .sif
```
### Run
#### Interactive
```bash
singularity shell --nv .sif
```
#### Application
```bash
singularity run --nv --app .sif []
```
## Docker
### Build
```bash
docker build -t .
```
It is possible to build a container from a specific file:
```bash
docker build -t -f .
```
### Save & Load
A [Docker](https://www.docker.com/) container can be saved
```
docker save -o ./.tar
```
and loaded on a differe host:
```
docker load -i ./.tar
```
### Run
#### Interactive
```
docker run --gpus all -ti /bin/bash
```
## Notes
### Singularity container from Docker container
[Singularity](https://sylabs.io/singularity/) images can be easily created from local Docker images as follows:
```bash
sudo singularity build .sif docker-daemon://
```
### `.dockerignore`
The `.dockerignore` file allows to ignore possible `*.tar` images (and other files) in the current directory, which would be included in the Docker context sent to the Docker deamon.
### Timenzone
Manual entry of the timezone is required when building containers. The following addition solves the issue:
```
ENV TZ=Europe/London
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
```
