How To Install Docker And Portainer On Rapid.Space
Agenda
- Install and start docker
- Download and run Portainer 2.0
- Enable IPv6 support in Docker daemon
- Verify listening port
- Access Portainer.io interface
Install and start docker
su -
apt install docker.io
systemctl start docker
You can check if docker is installed and activated by
root@rapidspace:~# docker --version
Docker version 18.09.1, build 4c52b90 # output
root@rapidspace:~# systemctl is-active docker
active #ouput
Download and run Portainer 2.0
docker pull portainer/portainer-ce
docker run --restart=always --name=portainer -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer-ce
You will get the similar output:
root@rapidspace:~# docker pull portainer/portainer-ce
Using default tag: latest #output
latest: Pulling from portainer/portainer-ce #output

Status: Image is up to date for portainer/portainer-ce:latest #output
root@rapidspace:~# docker run --restart=always --name=portainer -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock portainer/portainer-ce

You can also check your container: portainer by
docker stats
The sample output:
6d804c1f73a2 portainer 0.00% 11.26MiB / 236.2GiB 0.00% 3.5kB / 946B 0B / 403kB 21
Enable IPv6 support in Docker daemon
Edit the Docker configuration file
Edit /etc/docker/daemon.json
"fixed-cidr-v6"
should be a subnet of your IPv6 address:
{
"ipv6": true,
"fixed-cidr-v6": "2001:67c:1254:64:f8de:1111::1/96"
}
Save the file
Before you can use IPv6 in Docker containers or swarm services, you need to enable IPv6 support in the Docker daemon. Afterward, you can choose to use either IPv4 or IPv6 (or both) with any container, service, or network.
Note: IPv6 networking is only supported on Docker daemons running on Linux hosts.
Edit /etc/docker/daemon.json, set the ipv6 key to true and the fixed-cidr-v6 key to your IPv6 subnet. In this example we are setting it to 2001:67c:1254:64:f8de:1111::1/96
.
"fixed-cidr-v6"
should be a subnet of your IPv6 address (the one you use to ssh at the beginning). For example, if the IPv6 address is 2001:67c:1254:64:f8de::1, you are supposed to set it as 2001:67c:1254:64:f8de:xxxx::1/96
Enable IPv6 support in Docker daemon
Restart the Docker configuration file
systemctl restart docker
You can now create networks with the --ipv6
flag and assign containers IPv6 addresses using the --ip6
flag.
And if you check ip -6 a
, you will have docker0
with "fixed-cidr-v6"
which is a subnet of ens4
. (If you lose ens4
, try ifdown ens4 ; ifup ens4
to bring it back)
root@rapidspace:~# ip -6 a
......

Verify listening port
root@rapidspace:~# netstat -tnlp
Active Internet connections (only servers)
