fmriprep installation on Ubuntu

Install Docker

https://www.simplilearn.com/tutorials/docker-tutorial/how-to-install-docker-on-ubuntu

sudo apt-get install apt-transport

Uninstall old packages

for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

Set up the repository

Update the apt package index and install packages to allow apt to use a repository over HTTPS:
```
$ sudo apt-get update
$ sudo apt-get install ca-certificates curl gnupg
```

Add Docker's official GPG key:

$ sudo install -m 0755 -d /etc/apt/keyrings
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
$ sudo chmod a+r /etc/apt/keyrings/docker.gpg

Use the following command to set up the repository:

$ echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Note

If you use an Ubuntu derivative distro, such as Linux Mint, you may need to use UBUNTU_CODENAME instead of VERSION_CODENAME.

Update the apt package index:
```
$ sudo apt-get update
```

Install Docker Engine

Install Docker Engine, containerd, and Docker Compose.

Latest Specific version

To install the latest version, run:

 $ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Verify that the Docker Engine installation is successful by running the hello-world image.
```
$ sudo docker run hello-world
```
This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.

You have now successfully installed and started Docker Engine.

Add user to non-root group

https://www.thegeekdiary.com/run-docker-as-a-non-root-user/

sudo groupadd docker (probably already exists)

sudo usermod -aG docker [non-root user]

Tip: “whoami” returns current username

but, “docker” group is only for sudo…. (help) so in your user

newgrp docker

Log out and log back in so that your group membership is re-evaluated.

sudo docker pull nipreps/fmriprep

Install wrapper

pip install --user --upgrade fmriprep-docker

Add wrapper to path

sudo gedit .tcshrc

Add line

set path = ($path /home/[user]/.local/bin/)
