Calico for Containers

This repository is the home of calico/node and calicoctl.

Note that the documentation in this repo is targeted at Calico contributors.

Documentation for Calico users is here:

Building calico/node

To build the calico/node container, run the following build step from the root of the repository:

make calico/node

Use the build variables listed in the Calico binaries variable section at the top of the Makefile to modify which components are included in the resulting image. For example, the following command will produce a docker image called calico/node:custom which uses custom Felix and Libnetwork binaries:

FELIX_CONTAINER_NAME=calico/felix:1.4.3 \
LIBNETWORK_PLUGIN_CONTAINER_NAME=calico/libnetwork-plugin:v1.0.0-beta \
BUILD_CONTAINER_NAME=calico/node:custom \
make calico/node

Building calicoctl

There are two ways to build calicoctl: natively, and dockerized

Dockerized Builds

For simplicity, calicoctl can be built in a Docker container, eliminating the need for any dependencies in your host developer environment, using the following command:

make dist/calicoctl

The binary will be put in ./dist:

./dist/calicoctl --help

Native Builds

1. Assuming you have already installed go version 1.7.1+, ensure you've cloned this repository into your Go project path.

   git clone https://github.com/projectcalico/calicoctl.git $GOPATH/src/github.com/projectcalico/calicoctl
   

2. Install Glide.

3. Populate the vendor/ directory in the project's root with this project's dependencies:

   glide install -strip-vendor
   

4. Build the binary:

   make binary
   

Tests

Calico-containers system tests run in a container to ensure all build dependencies are met. Specifically, the calico/test image produced at https://github.com/projectcalico/libcalico is used.

The following Makefile step will use that image to run all local tests:

make st
