# Service deployment on a swarm
|
|
||||||
|
|
||||||
Script that create a swarm cluster and deploy a simple service.
|
|
||||||
Swarm is created with Swarm mode of Engine 1.12. Can be created on
|
|
||||||
* Virtualbox
|
|
||||||
* Microsoft Azure
|
|
||||||
* Digitalocean
|
|
||||||
* Amazon EC2
|
|
||||||
|
|
||||||
Note: currently, if deploying on AWS, only EU (Ireland) region is available. Make sure you use a Key Pairs for this region
|
|
||||||
|
|
||||||

# Example
|
|
||||||
|
|
||||||
Let's create a swarm cluster with 2 manager and 2 worker nodes locally (with virtualbox) and using service lucj/randomCity
|
|
||||||
Once deployed service will be available on port 8080 (default port)
|
|
||||||
|
|
||||||
```
|
|
||||||
$ ./swarm.sh --manager 2 --worker 2 --service_image lucj/randomCity --service_port 80
|
|
||||||
-> about to create a swarm with 2 manager(s) and 2 workers on virtualbox machines
|
|
||||||
-> creating Docker host for manager 1 (please wait)
|
|
||||||
-> creating Docker host for manager 2 (please wait)
|
|
||||||
-> creating Docker host for worker 1 (please wait)
|
|
||||||
-> creating Docker host for worker 2 (please wait)
|
|
||||||
-> init swarm
|
|
||||||
Swarm initialized: current node (99xi3bzlgobxmeff573qitctg) is now a manager.
|
|
||||||
-> join manager 2 to the swarm
|
|
||||||
Node f4wocnel60xwfn2z522a645ba accepted in the swarm.
|
|
||||||
-> join worker 1 to the swarm
|
|
||||||
This node joined a Swarm as a worker.
|
|
||||||
-> join worker 2 to the swarm
|
|
||||||
This node joined a Swarm as a worker.
|
|
||||||
-> deploy service with 5 replicas with exposed port 8080
|
|
||||||
-> waiting for service 5ny5u5pmfw75mnomleb34a3kp to be available

# Service details

|

The test service deployed is a simple http server that returns a message with

* the ip of the container that handled the request
|
|
||||||
* a random city of the world
|

# Test deployed service

Send several requests to the manager1
|
|

|
||||||
```
|
|
||||||
$ curl 192.168.99.100:8080

|
|
||||||
```
|
|
||||||
|
|
||||||
Send several requests to the worker2
|
|
||||||
|
|
||||||
```
|
|
||||||
$ curl http://192.168.99.102:8080

```
|
|
||||||
|
|
||||||
The requests are dispatched in a round robin fashion to the running containers.

# Examples with other drivers
|
|
||||||
|
|
||||||
## Run 3 managers and 6 workers on Microsoft Azure based on ehazlett/docker-demo image (default image if none specified)
|
|
||||||
|
|
||||||
```
|
|
||||||
./swarm.sh --driver azure --azure-subscription-id $AZURE_SUBSCRIPTION_ID --manager 3 --worker 6
|
|
||||||
```
|
|
||||||
|
|
||||||
## Run 3 managers and 6 workers on DigitalOcean and use service based on ehazlett/docker-demo image (default image if none specified)
|
|
||||||
|
|
||||||
```
|
|
||||||
./swarm.sh --driver digitalocean --digitalocean_token $DO_TOKEN --manager 3 --worker 6
|
|
||||||
```
|
|
||||||
|
|
||||||
Once the service is deployed you got some nice Mobydock :)
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
Note: beware of the browser cache that prevents the hostname to be updated sometimes
|
|
||||||
|
|
||||||
## Run 3 managers and 6 workers on AmazonEC2 based on ehazlett/docker-demo image (default image if none specified)
|
|
||||||
|
|
||||||
```
|
|
||||||
./swarm.sh --driver amazonec2 --amazonec2-access-key $AWS_ACCESS_KEY --amazonec2-secret-key $AWS_SECRET_KEY --amazonec2-security-group default --manager 3 --worker 6
|
|
||||||
```
|
|
||||||
|
|
||||||
note: make sure the security group provided (**default** in this example) allow communication between hosts and open the exposed port (8080 by default) to the outside
|
|
||||||

# docker swarm
|
|
||||||
|
|
||||||
Get in touch with the new `docker swarm` feature in Docker 1.12.
|
|
||||||
|
|
||||||
## Build a local swarm with Docker Machine
|
|
||||||
|
|
||||||
To create a local swarm with Docker Machine use the following script
|
|
||||||
|
|
||||||
```bash
|
|
||||||
./buildswarm-vbox.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
It will create two VirtualBox machines `sw01` and `sw02`. The machine `sw01` is
|
|
||||||
the swarm manager, the machine `sw02` joins the swarm.
|
|
||||||
|
|
||||||
To run further commands, just login to the machine `sw01` with
|
|
||||||
|
|
||||||
```bash
|
|
||||||
docker-machine ssh sw01
|
|
||||||
```
|
|
||||||
|
|
||||||
or run each command through ssh, eg.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
docker-machine ssh sw01 docker node ls
|
|
||||||
ID NAME MEMBERSHIP STATUS AVAILABILITY MANAGER STATUS LEADER
|
|
||||||
0j9p42jcyur9a * sw01 Accepted Ready Active Reachable Yes
|
|
||||||
16cznbhxupre5 sw02 Accepted Ready Active
|
|
||||||
```
|
|
||||||
|
|
||||||
### Remote swarm with Docker Machine at DigitalOcean
|
|
||||||
|
|
||||||
To build a multi machine swarm at DigitalOcean, run this script with your token.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
DO_TOKEN=xxxx ./buildswarm-do.sh
|
|
||||||
```
|
|
||||||
|
|
||||||
Then control your swarm with commands on your swarm manager node
|
|
||||||
|
|
||||||
```bash
|
|
||||||
docker-machine ssh do-sw01 docker node ls
|
|
||||||
```
