Intsall Rancher

• sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher

log in to ranhcer thorugh the web browser Add Cluster. Choose Custom. Enter a Cluster Name. Click Next. From Node Role, select all the roles: etcd, Control, and Worker. Copy the command displayed on screen to your clipboard. Log in to your Rancher host with PuTTy. Run the command copied to your clipboard. When you finish running the command on your Linux host, click Done. Wait for your cluster to finish provisioning Reboot to make sure everything is working right

Creating your first container

1. In your cluster drop down tab select default then deploy
2. give it a name and add the ports and env needed

Install Portainer with NFS share

sudo docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock --restart always --name portainer -v /mnt/appsNFS/portainer:/data portainer/portainer

select local

when adding volumes select bind and use the path /mnt/appsNFS/whateveryouwanthere

NFS Shares on FreeNAS

create a unix dataset called appsNFS with root and wheel as the user, set a quota for 50gb create a nfs share to the dtatset you created, select all dirs, mapall user:group to root:wheel enable nfs sharing and select nfsv4, allow non-root, nfsv3 owner ship reboot freenas

sudo ros config set mounts '[["10.68.69.2:/mnt/MyVol/appsNFS", "/home/rancher/appsNFS", "nfs4",""]]'

Add macvlan so containers are given an IP and mac from your LAN

Interesting. Thanks (⌐■_■)

just FYI newer versions of rancher require privileged access

docker run -d --restart=unless-stopped -p 80:80 -p 443:443 --privileged rancher/rancher:latest

Read what andrewiankidd wrote, i had to do the same,

also in the cloud-config file, change the position of console, as it throws error, i used the following

#cloud-config

hostname: rancher.homelab.com
rancher:
  console: centos
  network:
    interfaces:
      br0:
        bridge: true
        dhcp: false
        address: 192.168.0.19/24
        gateway: 192.168.0.1
        mtu: 1500
      eth0:
        bridge: br0
    dns:
      nameservers:
      - 8.8.8.8
      - 8.8.4.4
write_files:
  - path: /etc/rc.local
    permissions: "0755"
    owner: root
    content: |
      #!/bin/bash
      apt-get -y update
      apt-get -y install python
ssh_authorized_keys:
