# cn (ceph-nano)

![Ceph, the future of storage](https://raw.githubusercontent.com/ceph/cn/master/ceph-nano-logo-vertical.jpg)

## The project

cn is a little program written in Go that helps you interact with the S3 API by providing a REST S3 compatible gateway. The target audience is developers building their applications on Amazon S3. It is also an exciting tool to showcase Ceph Rados Gateway S3 compatibility.
This is brought to you by the power of Ceph and Containers. Under the hood, cn runs a Ceph container and exposes a [Rados Gateway](http://docs.ceph.com/docs/master/radosgw/). For convenience, cn also comes with a set of commands to work with the S3 gateway. Before you ask "why not using s3cmd instead?", then you will be happy to read that internally cn uses `s3cmd` and act as a wrapper around the most commonly used commands.
Also, keep in mind that the CLI is just for convenience, and the primary use case is you developing your application directly on the S3 API.

## Build

You can build `cn` by using `make`.
Be sure `dep` is installed:

```
$ go get github.com/golang/dep/cmd/dep
```

Then, add `~/go/bin` to your `$PATH`:

```
$ export PATH=$PATH:~/go/bin
```

Build `cn`:

```
$ make
rm -f cn cn &>/dev/null || true
dep ensure
GOOS=linux GOARCH=amd64 go build -i -ldflags="-X main.version=cea247c-dirty -X main.tag=devel -X main.branch=guits-doc_build" -o cn-devel-cea247c-dirty-linux-amd64 main.go
ln -sf "cn-devel-cea247c-dirty-linux-amd64" cn
```

Once the build is done, you should have a symlink `cn` pointing to the binary that just got built:

```
$ ls -l
total 10692
-rw-rw-r--. 1 guits guits    15292 20 nov.  22:03 ceph-nano-logo-vertical.jpg
drwxrwxr-x. 2 guits guits     4096 20 nov.  22:03 cmd
lrwxrwxrwx. 1 guits guits       34 20 nov.  22:27 cn -> cn-devel-cea247c-dirty-linux-amd64
-rwxrwxr-x. 1 guits guits 10881196 20 nov.  22:27 cn-devel-cea247c-dirty-linux-amd64
```

## Installation

cn relies on Docker so it must be installed on your machine. If you're not running a Linux workstation you can install [Docker for Mac](https://docs.docker.com/docker-for-mac/).

Once Docker is installed you're ready to start.
Open your terminal and download the cn binary.

macOS:

```
curl -L https://github.com/ceph/cn/releases/download/v2.3.1/cn-v2.3.1-darwin-amd64 -o cn && chmod +x cn
```

Linux amd64:

```
curl -L https://github.com/ceph/cn/releases/download/v2.3.1/cn-v2.3.1-linux-amd64 -o cn && chmod +x cn
```

Linux arm64:

```
curl -L https://github.com/ceph/cn/releases/download/v2.3.1/cn-v2.3.1-linux-arm64 -o cn && chmod +x cn
```

Test it out

```
$ ./cn

## Get started

Start the program with a working directory `/tmp`, the initial start might take a few minutes since we need to download the container image:

```
$ ./cn cluster start -d /tmp my-first-cluster
Running ceph-nano...
The container image is not present, pulling it.
This operation can take a few minutes......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Endpoint: http://10.36.116.164:8000
Dashboard: http://10.36.116.164:5001
Access key is: 9ZU1QBYX13KPLXXDDCY2
Secret key is: nthNG1xb7ta5IDKiJKM8626pQitqsalEo0ta7B9E
Working directory: /usr/share/ceph-nano
```

### Selecting the cluster flavor
Is it possible to select the cluster flavor by using the ``-f `` option on the command line.

```
$ ./cn cluster start mycluster -f huge
```

The full documentation of flavors can be found [here](CONFIGURATION.md)

## Your first S3 bucket

Create a bucket with `cn`:

```
$ ./cn s3 mb my-first-cluster my-buc
Bucket 's3://my-buc/' created

$ ./cn s3 put my-first-cluster /etc/passwd my-buc
upload: '/tmp/passwd' -> 's3://my-buc/passwd'  [1 of 1]
 5925 of 5925   100% in    1s     4.57 kB/s  done
 ```

## Multi-cluster support

`cn` can manage any number of clusters on your local machine:

```
$ ./cn cluster ls
+------+---------+-------------------------------------------------------------------------------------+----------------+--------------------------------+---------+
| NAME | STATUS  | IMAGE                                                                               | IMAGE RELEASE  | IMAGE CREATION TIME            | FLAVOR  |
+------+---------+-------------------------------------------------------------------------------------+----------------+--------------------------------+---------+
| d    | running | ceph/daemon:latest                                                                  | master-77e3d8d | 2018-04-05T15:01:40.323603472Z | default |
| b    | running | ceph/daemon@sha256:369867e450ccdea9bcea7f54e97ed8b2cb1a0437fbef658d2d01fce2b8a2c648 | master-5f44af9 | 2018-03-30T21:08:31.117367166Z | medium  |
+------+---------+-------------------------------------------------------------------------------------+----------------+--------------------------------+---------+
```

## List Ceph container images available

`cn` can list the available Ceph container images, the default output shows the 100 first images:

```
$ ./cn image ls
ceph/daemon:latest-mimic
ceph/daemon:latest-luminous
ceph/daemon:latest-master
ceph/daemon:master-0b3eb04-mimic-centos-7
ceph/daemon:master-0b3eb04-luminous-centos-7
ceph/daemon:master-0b3eb04-luminous-opensuse-42.3-x86_64
ceph/daemon:master-0b3eb04-master-centos-7-x86_64
ceph/daemon:master-0b3eb04-luminous-centos-7-x86_64
ceph/daemon:master-0b3eb04-mimic-centos-7-x86_64
[...]
```

### Using images aliases
The image option (`-i`) support aliases to simply the command line.
It is possible to list the aliases by running the `image show-aliases` command as per below :

```
$ ./cn image show-aliases
+----------+--------------------------------------------------+
| ALIAS    | IMAGE_NAME                                       |
+----------+--------------------------------------------------+
| mimic    | ceph/daemon:latest-mimic                         |
| luminous | ceph/daemon:latest-luminous                      |
| redhat   | registry.access.redhat.com/rhceph/rhceph-3-rhel7 |
+----------+--------------------------------------------------+
```
Aliases can be use in place of the traditional image name as per the following example:

```
$ ./cn cluster start mycluster -i mimic
```

It is also possible to create new aliases as detailed [here](CONFIGURATION.md)

## Enable mgr dashboard

### **TODO:** This is a **temporary hack** to enable the manager dashboard

Currently `cn` does not expose a port for the mgr dashboard.
It only exposes port 8000 for S3 API, and port 5000 for [Sree - S3 web client](https://github.com/cannium/Sree).
To expose also the mgr dashboard port we currently have to do some hacks.

This section will guide you how to manually commit a new image and then run a new container with the desired expose ports.

### Commit a copy of the docker image:
```
./cn cluster start temp -d /tmp
docker commit ceph-nano-temp ceph-nano
./cn cluster purge temp --yes-i-am-sure
```

### Run the container:
```
docker run -dt --name cn -p 8080:8080 -p 5000:5000 -p 8000:8000 ceph-nano
```

### Enable dashboard:
(Note: 'enable dashboard' command will cause the container to exit, so need to start it after)
```
docker exec cn ceph config set mgr mgr/dashboard/ssl false
docker exec cn ceph config set mgr mgr/dashboard/server_addr 0.0.0.0
docker exec cn ceph config set mgr mgr/dashboard/server_port 8080
docker exec cn ceph mgr module enable dashboard
until docker exec cn ceph; do docker start cn; sleep 1; done # wait for the services to start
docker exec cn ceph dashboard set-login-credentials nano nano
```

### Note that the Object Gateway tab in the dashboard is not enabled yet, so run the following to enable RGW dashboard:
```
RGW_USER=$(docker exec cn radosgw-admin user create --uid=rgw --display-name=rgw --system)
RGW_ACCESS=$(echo $RGW_USER | awk '{ for (i=1;i<=NF;++i) if ($i ~ /access_key/) { split($(i+1),a,"\""); print a[2] } }')
RGW_SECRET=$(echo $RGW_USER | awk '{ for (i=1;i<=NF;++i) if ($i ~ /secret_key/) { split($(i+1),a,"\""); print a[2] } }')
docker exec cn ceph dashboard set-rgw-api-access-key "$RGW_ACCESS"
docker exec cn ceph dashboard set-rgw-api-secret-key "$RGW_SECRET"
docker exec cn ceph dashboard set-rgw-api-host 127.0.0.1
docker exec cn ceph dashboard set-rgw-api-port 8000
docker exec cn ceph dashboard set-rgw-api-scheme http
docker exec cn ceph dashboard set-rgw-api-user-id rgw
```

### The dashboard should now be accessible:
- Open http://127.0.0.1:8080
- Login with user `nano` and password `nano`

### Troubleshooting - verify that your config dump should look like this:
```
$ docker exec cn ceph config dump
