for code, suggestions and documentation.
This page details a few notes, workflows and suggestions for how to make contributions most effective and help us
all build a better charm - please give them a read before working on any contributions.
## Licensing
This charm has been created under the [Apache License 2.0](./LICENSE), which will cover any contributions you may
make to this project. Please familiarise yourself with the terms of the license.
Additionally, this charm uses the Harmony CLA agreement. It’s the easiest way for you to give us permission to
use your contributions.
In effect, you’re giving us a license, but you still own the copyright — so you retain the right to modify your
code and use it in other projects. Please [sign the CLA here](https://ubuntu.com/legal/contributors/agreement) before
making any contributions.
## Code of conduct
We have adopted the Ubuntu code of Conduct. You can read this in full [here](https://ubuntu.com/community/code-of-conduct).
## Contributing code
The [DEVELOPING.md](./DEVELOPING.md) page has some useful information regarding building and testing. To contribute code
to this project, the workflow is as follows:
1. [Submit a bug](https://bugs.launchpad.net/charm-calico/+filebug) to explain the need for and track the change.
2. Create a branch on your fork of the repo with your changes, including a unit test covering the new or modified code.
3. Submit a PR. The PR description should include a link to the bug on Launchpad.

# Developing layer-calico
## Installing build dependencies
To install build dependencies:
```
sudo snap install charm --classic
sudo apt install docker.io
sudo usermod -aG docker $USER
```
After running these commands, terminate your shell session and start a new one
to pick up the modified user groups.
## Building the charm
To build the charm:
```
charm build
```
By default, this will build the charm and place it in
`/tmp/charm-builds/calico`.
## Building resources
To build resources:
```
./build-calico-resources.sh
```
This will produce several .tar.gz files that you will need to attach to the
charm when you deploy it.
## Testing
You can test a locally built calico charm by deploying it with Charmed
Kubernetes.
Create a file named `local-calico.yaml` that contains the following (with paths
adjusted to fit your environment):
```
applications:
calico:
charm: /tmp/charm-builds/calico
resources:
calico: /path/to/layer-calico/calico-amd64.tar.gz
calico-upgrade: /path/to/layer-calico/calico-upgrade-amd64.tar.gz
```
Then deploy Charmed Kubernetes with your locally built calico charm:
```
juju deploy cs:~containers/kubernetes-calico --overlay local-calico.yaml
```

# Calico Charm
Calico is a new approach to virtual networking and network security for containers,
VMs, and bare metal services, that provides a rich set of security enforcement
capabilities running on top of a highly scalable and efficient virtual network fabric.
This charm will deploy calico as a background service, and configure CNI for
use with calico, on any principal charm that implements the [kubernetes-cni][]
interface.
This charm is a component of Charmed Kubernetes. For full information,
please visit the [official Charmed Kubernetes docs](https://www.ubuntu.com/kubernetes/docs/charm-calico).

When set to true, if VXLAN encapsulation is in use, then the charm will
disable TX checksumming on the vxlan.calico network interface. This works
around an upstream issue in Calico:

# Overview
This interface layer handles the communication with Etcd via the `etcd`
interface.
# Usage
## Requires
This interface layer will set the following states, as appropriate:
* `{relation_name}.connected` The relation is established, but Etcd may not
yet have provided any connection or service information.
* `{relation_name}.available` Etcd has provided its connection string
information, and is ready to serve as a KV store.
The provided information can be accessed via the following methods:
* `etcd.get_connection_string()`
* `etcd.get_version()`
* `{relation_name}.tls.available` Etcd has provided the connection string
information, and the tls client credentials to communicate with it.
The client credentials can be accessed via:
* `{relation_name}.get_client_credentials()` returning a dictionary of
the clinet certificate, key and CA.
* `{relation_name}.save_client_credentials(key, cert, ca)` is a convenience
method to save the client certificate, key and CA to files of your
choosing.
For example, a common application for this is configuring an applications
backend key/value storage, like Docker.
```python
@when('etcd.available', 'docker.available')
def swarm_etcd_cluster_setup(etcd):
con_string = etcd.connection_string().replace('http', 'etcd')
opts = {}
opts['connection_string'] = con_string
render('docker-compose.yml', 'files/swarm/docker-compose.yml', opts)
```
## Provides
A charm providing this interface is providing the Etcd rest api service.
This interface layer will set the following states, as appropriate:
* `{relation_name}.connected` One or more clients of any type have
been related. The charm should call the following methods to provide the
appropriate information to the clients:
* `{relation_name}.set_connection_string(string, version)`
* `{relation_name}.set_client_credentials(key, cert, ca)`
Example:
```python
@when('db.connected')
def send_connection_details(db):
cert = leader_get('client_certificate')
key = leader_get('client_key')
ca = leader_get('certificate_authority')
# Set the key, cert, and ca on the db relation
db.set_client_credentials(key, cert, ca)
port = hookenv.config().get('port')
# Get all the peers participating in the cluster relation.
addresses = cluster.get_peer_addresses()
connections = []
for address in addresses:
connections.append('http://{0}:{1}'.format(address, port))
# Set the connection string on the db relation.
db.set_connection_string(','.join(conections))
```
