Release Notes - 201911

release-201911.5

From this release, you don't have to set up setaria component, which was used for performing analyses. Instead, Sider runs runners with Docker directly. Runners are just containers that perform analyses and they were executed by setaria component before. You should still take care of the Docker host performance issues, but direct usage by Sider reduces the maintenance of another component.

In addition, the way of downloading Docker images has changed. AWS credentials (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) are required when downloading images and the image names are also changed. See Pulling images for more details.

How to upgrade

If you set up Sider with docker-compose, removes setaria_web and setaria_worker services from the docker-compose.yml. Also, you must allow sideci_worker to call Docker API. If you want to sideci_worker to access Docker via Unix socket, don't forget to attach Docker socket (e.g. /var/run/docker.sock:/var/run/docker.sock:ro).

To upgrade to this release, the following environment variables are newly needed.

• RUNNERS_TRACES_S3_BUCKET_NAME
• DOCKER_RUNNERS_CONFIG
