About
TODO: Insert comprehensive feature list of the bridgehead? Why would anyone install it?
Projects
GBA/BBMRI-ERIC
The Sample Locator is a tool that allows researchers to make searches for samples over a large number of geographically distributed biobanks. Each biobank runs a so-called Bridgehead at its site, which makes it visible to the Sample Locator. The Bridgehead is designed to give a high degree of protection to patient data. Additionally, a tool called the [Negotiator][negotiator] puts you in complete control over which samples and which data are delivered to which researcher.
You will most likely want to make your biobanks visible via the [publicly accessible Sample Locator][sl], but the possibility also exists to install your own Sample Locator for your site or organization, see the GitHub pages for [the server][sl-server-src] and [the GUI][sl-ui-src].
The Bridgehead has two primary components:
- The Blaze Store. This is a highly responsive FHIR data store, which you will need to fill with your data via an ETL chain.
- The Connector. This is the communication portal to the Sample Locator, with specially designed features that make it possible to run it behind a corporate firewall without making any compromises on security.

Blaze Server
This holds the actual data being searched. This store must be filled by you, generally by running an ETL on your locally stored data to turn it into the standardized FHIR format that we require.

Requirements
Hardware
For running your bridgehead we recommend the follwing Hardware:
- 4 CPU cores
- At least 8 GB Ram
- 100GB Hard Drive, SSD recommended
System Requirements
Before starting the installation process, please ensure that following software is available on your system:
Git
Check if you have at leat git 2.0 installed on the system with:
git --version
Docker
To check your docker installation, you should execute the docker with --version:
docker --version
The Version should be higher than "20.10.1". Otherwise you will have problems starting the bridgehead. The next step is to check docker-compose with:
docker-compose --version
The recomended version is "2.XX" and higher. If docker-compose was not installed with docker follow these instructions. To futher check your docker and docker-compose installation, please run the following command.
docker-compose -f - up <<EOF
version: "3.7"
services:
hello-world:
image: hello-world
EOF
Docker will now download the "hello-world" docker image and try to execute it. After the download you should see a message starting with "Hello from Docker!".
NOTE: If the download of the image fails (e.g with "connection timed out" message), ensure that you have correctly set the proxy for the docker daemon. Refer to "Docker Daemon Proxy Configuration" in the "Pitfalls" section
systemd
You shouldn't need to install it yourself, If systemd is not available on your system you should get another system. To check if systemd is available on your system, please execute
systemctl --version
If systemd is not installed, you can start the bridgehead. However, for productive use we recomend using systemd.
Getting Started
Installation
If your system passed all checks from ["Requirements" section], you are now ready to download the bridgehead.
First, clone the repository to the directory "/srv/docker/bridgehead":
sudo mkdir -p /srv/docker/;
sudo git clone https://github.com/samply/bridgehead.git /srv/docker/bridgehead;
It is recomended to create a user for the bridgehead service. This should be done after clone the repository. Since not all linux distros support adduser, we provide an action for the systemcall useradd. You should try the first one, when the systm can't create the user you should try the second one.
adduser --no-create-home --disabled-login --ingroup docker --gecos "" bridgehead
useradd -M -g docker -N -s /sbin/nologin bridgehead
After adding the User you need to change the ownership of the directory to the bridgehead user.
chown bridgehead /srv/docker/bridgehead/ -R
Configuration
NOTE: If you are part of the CCP-IT we will provide you another link for the configuration.
Next, you need to configure a set of variables, specific for your site with not so high security concerns. You can clone the configuration template at GitHub. The confiugration of the bridgehead should be located in /etc/bridghead.
sudo git clone https://github.com/samply/bridgehead-config.git /etc/bridgehead;
After cloning or forking the repository you need to add value to the template. If you are a part of the CCP-IT you will get an already filled out config repo.
Testing your bridgehead
We recomend to run first with the start and stop script. If you have trouble starting the bridghead have a look at the troubleshooting section.
Now you ready to run a bridgehead instance. The bridgehead scripts checks if your configuration is correct. To check if everything works, execute the following:
/srv/docker/bridgehead/bridgehead start <Project>
You should now be able to access the landing page on your system, e.g "https:///".
To shutdown the bridgehead just run.
/srv/docker/bridgehead/bridgehead stop <Project>
Systemd service configuration
For a server, we highly recommend that you install the system units for managing the bridgehead, provided by us. You can do this by executing the bridgehead script:
sudo /srv/docker/bridgehead/bridgehead install <Project>
This will install the systemd units to run and update the bridghead.
Finally, you need to configure your sites secrets. These are places as configuration for each bridgehead system unit. Refer to the section for your specific project:
For Every project you need to set the proxy this way, if you have one. This is done with the systemctl edit comand.
sudo systemctl edit bridgehead@<project>.service;
sudo systemctl edit bridgehead-update@<project>.service;
[Service]
Environment=http_proxy=<proxy-url>
Environment=https_proxy=<proxy-url>
There a further configurations for each project.
CCP(DKTK/C4)
For the federate search please follow the basic auth configuration step.
DKTK/C4
You can create the site specific configuration with:
This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets. You share some of the ID-Management secrets with the central patientlist (Mainz) and controlnumbergenerator (Frankfurt). Refer to the "Configuration" section for this.
[Service]
Environment=http_proxy=
Environment=https_proxy=
To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:
sudo systemctl daemon-reload;
sudo systemctl bridgehead@ccp.service;
You can create the site specific configuration with:
sudo systemctl edit bridgehead@c4.service;
This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets. You share some of the ID-Management secrets with the central patientlist (Mainz) and controlnumbergenerator (Frankfurt). Refer to the "Configuration" section for this.
[Service]

To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:
sudo systemctl daemon-reload;
sudo systemctl bridgehead@c4.service;
GBA/BBMRI-ERIC
You can create the site specific configuration with:
sudo systemctl edit bridgehead@gbn.service;
This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor and define your machines secrets.
[Service]
Environment=HOSTIP=
Environment=HOST=
Environment=HTTP_PROXY_USER=
Environment=HTTP_PROXY_PASSWORD=
Environment=HTTPS_PROXY_USER=
Environment=HTTPS_PROXY_PASSWORD=
Environment=CONNECTOR_POSTGRES_PASS=
To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:
sudo systemctl daemon-reload;
sudo systemctl bridgehead@gbn.service;
Configuration
Basic Auth
For Data protection we use basic authenfication for some services. To access those services you need an username and password combination. If you start the bridgehead without basic auth, then those services are not accesbile. We provide a script which set the needed config for you, just run the script and follow the instructions.
add_user.sh
The result needs to be set in either in the systemd service or in your console.
Console
When just running the bridgehead you need to export the auth variable. Be aware that this export is only for the current session in the environment and after exit it will not be accessible anymore.
export bc_auth_user=<output>
Cation: you need to escape occrring dollar signs.
systemd
HTTPS Access
We advise to use https for all service of your bridgehead. HTTPS is enabled on default. For starting the bridghead you need a ssl certificate. You can either create it yourself or get a signed one. You need to drop the certificates in /certs.
The bridgehead create one autotmatic on the first start. However, it will be unsigned and we recomend to get a signed one.

Managing your Bridgehead
TODO: Rewrite this section (restart, stop, uninstall, manual updates)
On a Server
Start
This will start a not running bridgehead system unit:
sudo systemctl start bridgehead@<dktk/c4/gbn>
Stop
This will stop a running bridgehead system unit:
sudo systemctl stop bridgehead@<dktk/c4/gbn>
Update
This will update bridgehead system unit:
sudo systemctl start bridgehead-update@<dktk/c4/gbn>
Remove the Bridgehead System Units
If, for some reason you want to remove the installed bridgehead units, we added a command to bridgehead:
sudo /srv/docker/bridgehead/bridgehead uninstall <project>
On Developers Machine
For developers, we provide additional scripts for starting and stopping the specif bridgehead:
Start or stop
This command starts a specified bridgehead. Choose between "dktk", "c4" and "gbn".
/srv/docker/bridgehead/bridgehead start <dktk/c4/gbn>
Stop
This command stops a specified bridgehead. Choose between "dktk", "c4" and "gbn".
/srv/docker/bridgehead/bridgehead stop <dktk/c4/gbn>
Update
This shell script updates the configuration for all bridgeheads installed on your system.
/srv/docker/bridgehead/bridgehead update
NOTE: If you want to regularly update your developing instance, you can create a CRON job that executes this script.

Pitfalls
Git Proxy Configuration
Unlike most other tools, git doesn't use the default proxy variables "http_proxy" and "https_proxy". To make git use a proxy, you will need to adjust the global git configuration:
sudo git config --global http.proxy http://<your-proxy-host>:<your-proxy-port>;
sudo git config --global https.proxy http://<your-proxy-host>:<your-proxy-port>;
NOTE: Some proxies may require user and password authentication. You can adjust the settings like this: "http://:@:". NOTE: It is also possible that a proxy requires https protocol, so you can replace this to.
You can check that the updated configuration with
sudo git config --global --list;
Docker Daemon Proxy Configuration
Docker has a background daemon, responsible for downloading images and starting them. To configure the proxy for this daemon, use the systemctl command:
sudo systemctl edit docker
This will open your default editor allowing you to edit the docker system units configuration. Insert the following lines in the editor, replace and with the corresponding values for your machine and save the file:
[Service]
Environment=HTTP_PROXY=http://<your-proxy-host>:<your-proxy-port>
Environment=HTTPS_PROXY=http://<your-proxy-host>:<your-proxy-port>
Environment=FTP_PROXY=http://<your-proxy-host>:<your-proxy-port>
NOTE: Some proxies may require user and password authentication. You can adjust the settings like this: "http://:@:". NOTE: It is also possible that a proxy requires https protocol, so you can replace this to.
The file should now be at the location "/etc/systemd/system/docker.service.d/override.conf". You can proof check with
cat /etc/systemd/system/docker.service.d/override.conf;
To make the configuration effective, you need to tell systemd to reload the configuration and restart the docker service:
sudo systemctl daemon-reload;
sudo systemctl restart docker;
After the Installtion
After starting your bridgehead, visit the landing page under the hostname. If you singed your own ssl certificate, there is probable an error message. However, you can accept it as exception.
On this page, there are all important links to each component, central and local.
Connector Administration
The Connector administration panel allows you to set many of the parameters regulating your Bridgehead. Most especially, it is the place where you can register your site with the Sample Locator. To access this page, proceed as follows:
- Open the Connector page: https:///-connector/
- In the "Local components" box, click the "Samply Share" button.
- A new page will be opened, where you will need to log in using the administrator credentials (admin/adminpass by default).
- After log in, you will be taken to the administration dashboard, allowing you to configure the Connector.
- If this is the first time you have logged in as an administrator, you are strongly recommended to set a more secure password! You can use the "Users" button on the dashboard to do this.

Register with a Directory
The [Directory][directory] is a BBMRI project that aims to catalog all biobanks in Europe and beyond. Each biobank is given its own unique ID and the Directory maintains counts of the number of donors and the number of samples held at each biobank. You are strongly encouraged to register with the Directory, because this opens the door to further services, such as the [Negotiator][negotiator].
Generally, you should register with the BBMRI national node for the country where your biobank is based. You can find a list of contacts for the national nodes here. If your country is not in this list, or you have any questions, please contact the BBMRI helpdesk. If your biobank is for COVID samples, you can also take advantage of an accelerated registration process here.
Your national node will give you detailed instructions for registering, but for your information, here are the basic steps:
- Log in to the Directory for your country.
- Add your biobank and enter its details, including contact information for a person involved in running the biobank.
- You will need to create at least one collection.
- Note the biobank ID and the collection ID that you have created - these will be needed when you register with the Locator (see below).
Register with a Locator
- Go to the registration page http://localhost:8082/admin/broker_list.xhtml.
- To register with a Locator, enter the following values in the three fields under "Join new Searchbroker":
- "Address": Depends on which Locator you want to register with:
https://locator.bbmri-eric.eu/broker/: BBMRI Locator production service (European).http://147.251.124.125:8088/broker/: BBMRI Locator test service (European).https://samplelocator.bbmri.de/broker/: GBA Sample Locator production service (German).https://samplelocator.test.bbmri.de/broker/: GBA Sample Locator test service (German).
- "Your email address": this is the email to which the registration token will be returned.
- "Automatic reply": Set this to be
Total Size
- "Address": Depends on which Locator you want to register with:
- Click "Join" to start the registration process.
- You should now have a list containing exactly one broker. You will notice that the "Status" box is empty.
- Send an email to
feedback@germanbiobanknode.deand let us know which of our Sample Locators you would like to register to. Please include the biobank ID and the collection ID from your Directory registration, if you have these available. - We will send you a registration token per email.
- You will then re-open the Connector and enter the token into the "Status" box.
- You should send us an email to let us know that you have done this.
- We will then complete the registration process
- We will email you to let you know that your biobank is now visible in the Sample Locator.
If you are a Sample Locator administrator, you will need to understand the registration process. Normal bridgehead admins do not need to worry about this.
