Known issues

ERROR: Couldn't connect to Docker daemon at http+docker://localunixsocket - is it running?

# Solution
sudo service docker start

docker Err http://deb.debian.org Jessie InRelease

• Try to execute the command nslookup duckduckgo.com 8.8.8.8 . If the message ;; connection timed out; no servers could be reached appears

• Then edit your daemon.json

# sudo vim /etc/docker/daemon.json

{
    "dns": ["8.8.8.8", "8.8.4.4"]
}

• Restart the Docker service

sudo service docker restart

Docker build “Could not resolve ‘archive.ubuntu.com’” apt-get fails to install anything

This doesn't address the underlying issue, but I had success adding --network=host to the docker build command.

sudo docker build --network=host -t my-docker-image .. 

By default Docker uses 172.17.0.0/16. This can conflict with the IP range you use for your cloud subnet range

By default Docker uses 172.17.0.0/16. This can conflict with the IP range you use for your cloud subnet range

Step 1: SSH into the Hyperglance Instance/VM

Step 2: edit /etc/docker/daemon.json

You need to add "bip": "172.26.0.1/16" to the JSON in daemon.json

The JSON will look like this after you amend. NOTE remember to add the ',' at the end of the second last '}'.

$ sudo vim /etc/docker/daemon.json

{
  "log-driver": "journald",
  "log-opts": {
    "tag": "{{.Name}}"
  },
  "bip": "172.26.0.1/16"
}

Step 3: Restart Docker

sudo systemctl restart docker

Step 4: Check the routing table

netstat -rn

# Kernel IP routing table
# Destination Gateway Genmask Flags MSS Window irtt Iface
# 0.0.0.0 172.31.16.1 0.0.0.0 UG 0 0 0 eth0
# 169.254.169.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
# 172.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 br-e9768d205a82
# 172.26.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0
# 172.31.16.0 0.0.0.0 255.255.240.0 U 0 0 0 eth0

The docker containers will restart and it should then start to collect!

Could not find an available, non-overlapping IPv4 address pool among the defaults to assign to the network

sudo service network-manager restart

Note: when using OpenVPN, disable it first.
