Docker CAT

Workflow CI Badge Workflow CD Badge Docker Image Version (tag latest)

Docker Code Analysis Tool (CAT) is a SonarQube Docker image containing custom configuration and plugins to realize code analysis.

SonarQube is an open platform to manage code quality.

This project is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 3 of the License, or (at your option) any later version.

You can get SonarQube on GitHub: SonarSource/sonarqube.

Quick install

  1. Find group IDs to allow SonarQube analysis to (for Sonar CNES Scan plugin):

    • Using getent group <group_name> | cut -d : -f3 to reach a group id from a known group name;
    • Using cat /etc/group to list all group IDs.

    ❗ This group should have read and execution permissions on all the project to analyze (to browse and analyze all files) and write permissions on the root of the workspace (to execute C/C++ tools and sonar-scanner).

  2. Find the version you want to use on DockerHub: https://hub.docker.com/r/lequal/docker-cat or simply use the latest image which correspond to the master branch of this project.

  3. Run the Docker CAT container:

docker pull lequal/docker-cat
docker run --rm --name=cat -v <your_folder>:/media/sf_Shared:rw -p 9000:9000 -e ALLOWED_GROUPS="<GID_1>;<GID_2>;<GID_...>" lequal/docker-cat:<version>

❗ This example use --rm option so when the container will stop and will be destroyed with all its data.

❗ Avoid using 0 as GUID (e.g.: -e ALLOWED_GROUPS=0): it can cause conflicts with container's root user.

Advanced configuration

Default account

You can log in Docker CAT's SonarQube as administrator with the default SonarQube credentials. As it is not secured (everybody knows it!), be sure to run Docker CAT in a secured environment or change the default credentials.

  • username: admin
  • password: admin

As administrator you are able to change any configuration you want as default values, activated rules or quality gate conditions...

Persisting your Docker CAT instance

By default, Docker CAT use the embedded H2 database which is integrated to SonarQube: it should not be use for long term use. That's why if you expect to keep your data for a while, you should consider setting up a stronger database as described in the official documentation.

Analyzing source code

Using web user interface

Once the container is active, you can use the web interface provided by Sonar CNES Scan plugin to run an analysis directly via your Web browser. #TODO

1. If not already done, move your code in <your_folder>

To be reachable by all included tools, your source code must be placed in the previously mounted Docker volume and the group whose GUID has been given to -e ALLOWED_GROUPS=... parameter should have permissions on the whole directory.

❗ If you encounter some difficulties with permissions on files in mounted volumes (due to your system configuration) you can directly copy your code into the container. Execute the docker run command by removing any -v or --volume options and copy your directory in the directory /media/sf_Shared of the container by using this command docker cp <my_directory> cat:/media/sf_Shared.

2. Go to Docker CAT web interface

Just open your favourite web browser and access the SonarQube interface by typing the Docker CAT IP/URL followed by : and the port mapped to the port 9000 of the container. If you start Docker CAT on your workstation with the default previously proposed command you should have type http://localhost:9000 in your address bar.

3. Go to CNES Analysis page

When SonarQube has loaded, click on More in the black upper toolbar and select CNES Analysis. A new page should appear with the analysis form.

CNES Analysis menu

4. Fill in the form

Fill in the form by paying attention to:

  • fields with a red asterisk: they are mandatory
  • Workspace fields: by default let a point . in this field. If you want to limit the scope of the analysis, type the relative path from the /mnt/sf_Shared directory.
  • Workspace fields: by default let a point . in this field. If you want to limit the files/path considered as source files (by opposition to test files), type a coma-separated list of relative path starting from the Workspace directory.
  • Run C/C++ tools: turn on ths button if you want to run embedded tools (cppcheck, vera++ and rats). If you analyze C or C++ code and you already have cppcheck, vera++ or rats results in your working directory you can use the sonar-project.properties field to designate the location of these results and turn off the analysis. Refer to sonar-cxx documentation for further information.
  • sonar-project.properties field: use this field to add more advanced configuration. Refer to official documentation.

CNES Analysis form

5. Run the analysis

Just click on the Analyze button on the bottom of the page to run the analysis. When successfully run, an archive download should start in your web browser. It contains all the results of your analysis. If you already have analysis in your CAT instance, you can regenerate the report without rerunning analysis by using form in More > CNES Report.

Using classical way

You can run an analysis with the classic method by using one of scanners provided by SonarSource. You simply have to give the URL or IP where Docker CAT has been launched and the matching port you give in your docker command for port 9000. For more information use SonarSource's scanners as described in the official documentation.

❗ With these methods, autolaunched tool like cppcheck may not work, if they are not correctly set.
