Version
$ ./bin/matchbox -version
$ sudo docker run quay.io/poseidon/matchbox:latest -version
Usage
Run the binary.
$ ./bin/matchbox -address=0.0.0.0:8080 -log-level=debug -data-path=examples -assets-path=examples/assets
Run the latest Docker image.
$ sudo docker run -p 8080:8080 --rm -v $PWD/examples/assets:/var/lib/matchbox/assets:Z quay.io/poseidon/matchbox:latest -address=0.0.0.0:8080 -log-level=debug
With examples
Mount examples to pre-load the example machine groups and profiles. Run the container.
$ sudo docker run -p 8080:8080 --rm -v $PWD/examples:/var/lib/matchbox:Z -v $PWD/examples/groups/etcd:/var/lib/matchbox/groups:Z quay.io/poseidon/matchbox:latest -address=0.0.0.0:8080 -log-level=debug
With gRPC API
The gRPC API allows clients with a TLS client certificate and key to make RPC requests to programmatically create or update matchbox resources. The API can be enabled with the -rpc-address flag and by providing a TLS server certificate and key with -cert-file and -key-file and a CA certificate for authenticating clients with -ca-file.
Run the binary with TLS credentials from examples/etc/matchbox.
$ ./bin/matchbox -address=0.0.0.0:8080 -rpc-address=0.0.0.0:8081 -log-level=debug -data-path=examples -assets-path=examples/assets -cert-file examples/etc/matchbox/server.crt -key-file examples/etc/matchbox/server.key -ca-file examples/etc/matchbox/ca.crt
Clients, such as bootcmd, verify the server's certificate with a CA bundle passed via -ca-file and present a client certificate and key via -cert-file and -key-file to cal the gRPC API.
$ ./bin/bootcmd profile list --endpoints 127.0.0.1:8081 --ca-file examples/etc/matchbox/ca.crt --cert-file examples/etc/matchbox/client.crt --key-file examples/etc/matchbox/client.key
With docker
Run the Docker image with TLS credentials from examples/etc/matchbox.
$ sudo docker run -p 8080:8080 -p 8081:8081 --rm -v $PWD/examples:/var/lib/matchbox:Z -v $PWD/examples/etc/matchbox:/etc/matchbox:Z,ro -v $PWD/examples/groups/etcd:/var/lib/matchbox/groups:Z quay.io/poseidon/matchbox:latest -address=0.0.0.0:8080 -rpc-address=0.0.0.0:8081 -log-level=debug
A bootcmd client can call the gRPC API running at the IP used in the Docker example.
$ ./bin/bootcmd profile list --endpoints 127.0.0.1:8081 --ca-file examples/etc/matchbox/ca.crt --cert-file examples/etc/matchbox/client.crt --key-file examples/etc/matchbox/client.key
With openPGP Signing
Run with the binary with a test key.
$ export MATCHBOX_PASSPHRASE=test
$ ./bin/matchbox -address=0.0.0.0:8080 -key-ring-path matchbox/sign/fixtures/secring.gpg -data-path=examples -assets-path=examples/assets
Run the container image with a test key.
$ sudo docker run -p 8080:8080 --rm --env MATCHBOX_PASSPHRASE=test -v $PWD/examples:/var/lib/matchbox:Z -v $PWD/examples/groups/etcd:/var/lib/matchbox/groups:Z -v $PWD/matchbox/sign/fixtures:/secrets:Z quay.io/poseidon/matchbox:latest -address=0.0.0.0:8080 -log-level=debug -key-ring-path secrets/secring.gpg
