Docker support for srsLTE

This repository contains Dockerfiles to build images and deploy containers for srsLTE with Universal Software Radio Peripheral (USRP™) SDR frontend support.

By using Docker image there is no need to install build dependencies on the host.

The srsLTE can be easily deployed for different front-end devices and driver versions. srsLTE images can be tagged differently for testing and deployment.

Folders uhd and srslte contain base images for Ettus UHD and srsLTE dependencies correspondingly.

Folder scripts contains useful scripts to build containers and perform build and run operations.

Requirements

• Docker 18

TODO

• Add namings and tags description to the README
• Add srsGUI support
• Extract binaries from docker container to the README
• Create a production build

Dockerfile Example

The following Dockerfile is building srsLTE:

FROM igorskh/srslte

ARG WORKFOLDER=./
ARG SERVICE_FOLDER=srslte

COPY $WORKFOLDER /$SERVICE_FOLDER
RUN rm -rf /$SERVICE_FOLDER/build
RUN mkdir /$SERVICE_FOLDER/build
WORKDIR /$SERVICE_FOLDER/build
RUN cmake ../ &&\
    make

Image igorskh/srslte contains necessary dependencies, corresponding Dockerfile is located in srslte_uhd. For other UHD versions new image has to be generated.

Build srsLTE

Build script is located in scripts/build.sh, with prepared Dockerfile it can be used as following

~/srslte-docker/scripts/build.sh \
    --container=srslte-app \
    --service=srslte \
    --root=$(pwd) \
    --image=igorskh/srslte-app \
    --config-path-host=~/dev/srsLTE/srslte-config \
    --config-path-cont=/root/.config/srslte \
    --gui=true

~/srslte-docker is location of this repository.

The arguments are the following:

• --container - a container name
• --service - a subfolder name which will be created in the root of the
• --root - the location of the srsLTE repository
• --image - the Docker image name which will be given to the built image
• --config-path-host - location of the configuration files folder on the host
• --config-path-cont - location of the configuration files folder in the container
• --gui - enable X11 passthrough to the container if true

The same script can be used for rebuilding the source code, the build folder will be preserved.

Run srsLTE in Docker

Run script is located in scripts/build.sh

Example:

~/srslte-docker/run.sh \
    --container=srslte-app \
    --app=srsenb \
    --root=build/srsenb/src \
    --service=srslte

The arguments are the following:

• --container - a container name, should be same as for the build step
• --app - executable name
• --root - path relative to the /$service
• --service - service name, should be the same as for the build step

In this example the script will run /srslte/build/srsenb/src/srsenb executable.

Automatization for Visual Studio Code

File example.tasks.json contains tasks for the VS Code to build and run srsLTE.

The file should be placed in the .vscode folder of the project such as:

cp example.tasks.json ../.vscode/tasks.json

Then tasks can be called as Ctrl+Shift+P -> Tasks: Run task -> Choose task here.

OPTIONAL: Build the base UHD image

By default the base image containing the UHD installation is:

cd uhd
docker build -t uhd:latest .

This will create an uhd:latest docker image.

Optionally the version of the UHD can be passed as

docker build --build-arg uhd_tag=release_003_010_003_000 .

Images srsENB and srsUE will use this base image.
