Docker Multi Containers

This tutorial highlights the netns sharing and ip.netns driver.

The service created will have a shared netns held by the google/pause container, where the ip.netns driver will plumb an ipvlan-l2 ip address.

Pre-requisites

Provision

Let’s use the following stack as an example:

  • google/pause

  • nginx

  • redis

cat - <<EOF | om svc2 create --config=- --provision --local
{
        "DEFAULT": {
                "id": "fd1196ad-fbf1-49bb-ab52-12ed2a1fbf0e"
        },
        "container#1": {
                "image": "google/pause",
                "run_command": "/bin/sh",
                "type": "docker"
        },
        "container#2": {
                "image": "nginx",
                "netns": "container#1",
                "type": "docker"
        },
        "container#3": {
                "image": "redis",
                "netns": "container#1",
                "type": "docker"
        },
        "ip#1": {
                "gateway": "5.196.34.158",
                "ipdev": "eth0",

                "netns": "container#1",

Containers Management

All containers

It is possible to manage containers together, either start or stop, by using the start --rid container or stop --rid container OpenSVC keywords.

root@deb1:/opt/opensvc# svc2 stop --rid container

Note

the ip#1 resource, being dependent of container#1, is also selected for stop and for start.

Single container

Like any other OpenSVC resource in the service configuration file, it is possible to manage it with its resource id, using the --rid <resource_id> option.

root@deb1:/# om svc2 restart --rid container#3
deb1.opensvc.com.svc2.container#3   docker stop 1bf08bf890635aa334d22a0a040e03861def0fbcc9635e39cf352a517b7045ac

deb1.opensvc.com.svc2.container#3   wait for up status
deb1.opensvc.com.svc2.container#3   wait for container operational

Container Upgrade

Switch container#3 image to tag 3.0:

root@deb1:/opt/opensvc# svc2 set --kw container#3.rm=true --kw container#3.image=redis:3.0

Note

container#3.rm=true causes the agent to remove the instance after stop, so a new instance based on the changed image will be spawn on the following start.

And restart:

root@deb1:/opt/opensvc# svc2 restart --rid container#3
deb1.opensvc.com.svc2.container#3   docker stop 1bf08bf890635aa334d22a0a040e03861def0fbcc9635e39cf352a517b7045ac

Complex Orchestration

When implementing applications as Docker containers, you may need to organize the containers startup in a specific order or benefit from starting multiple containers in parrallel.

The following example describes:

  • 1 database server : this container have to be started first, and stopped at the very end.

  • 4 application servers : those containers have to be started in parrallel, and just after the database server.

  • 2 webservers : last to be launched, just after the appservers.

To get straight to the point, all containers will use the opensvc/busybox image.

Note

If one of the container startup fails, the action is rolled back.

OpenSVC Syntax

This service will highligth two configuration mecanisms:

  • Assigning a resource to a subset:

    [container#<n>]
    subset = 01appservers
    
  • Optionaly, configuring a subset for starting its resources in parallel:

    [subset#container.docker:01appservers]
    parallel = true
    

Subsets are processed in alphanumerical order.

Example

Example service configuration file

parallel = false

[ip#1]
ipdev = eth0

[vg#1]
vgname = vgbusybox
scsireserv = false

[fs#1]

[fs#2]
mnt_opt = rw
mnt = /opt/busybox.opensvc.com/appdata
dev = /dev/mapper/vgbusybox-lvbusyboxdata

Service startup

Actions are processed in the following order

  • ip/vg/fs start

  • subset 00database start

  • subset 01appservers parallel start

  • subset 02webservers sequential start
