Fenrir makes a call to the database at a configurable interval. The database call tells the database to delete records whose deathdate has passed, but there is a configurable limit to the number of records to delete, to avoid timeout issues.
In order to build from the source, you need a working Go environment with version 1.11 or greater. Find more information on the Go website.
You can directly use
go get to put the Fenrir binary into your
GO111MODULE=on go get github.com/xmidt-org/fenrir
You can also clone the repository yourself and build using make:
mkdir -p $GOPATH/src/github.com/xmidt-org cd $GOPATH/src/github.com/xmidt-org git clone firstname.lastname@example.org:Comcast/fenrir.git cd fenrir make build
The Makefile has the following options you may find helpful:
make build: builds the Fenrir binary
make rpm: builds an rpm containing Fenrir
make docker: builds a docker image for Fenrir, making sure to get all dependencies
make local-docker: builds a docker image for Fenrir with the assumption that the dependencies can be found already
make it: runs
make docker, then deploys Fenrir and a cockroachdb database into docker.
make test: runs unit tests with coverage for Fenrir
make clean: deletes previously-built binaries and object files
The docker image can be built either with the Makefile or by running a docker command. Either option requires first getting the source code.
See Makefile on specifics of how to build the image that way.
For running a command, either you can run
docker build after getting all
dependencies, or make the command fetch the dependencies. If you don't want to
get the dependencies, run the following command:
docker build -t fenrir:local -f deploy/Dockerfile .
If you want to get the dependencies then build, run the following commands:
GO111MODULE=on go mod vendor docker build -t fenrir:local -f deploy/Dockerfile.local .
For either command, if you want the tag to be a version instead of
local in the
docker build command.
WIP. TODO: add info
For deploying on Docker or in Kubernetes, refer to the deploy README.
For running locally, ensure you have the binary built. If it's in
If the binary is in your current folder, run:
