Redis based IP blacklist for Nginx (LUA)
-- a quick LUA access script for nginx to check IP addresses against an
-- `ip_blacklist` set in Redis, and if a match is found send a HTTP 403.
--
-- allows for a common blacklist to be shared between a bunch of nginx
-- web servers using a remote redis instance. lookups are cached for a
-- configurable period of time.
--
-- block an ip:
-- redis-cli SADD ip_blacklist 10.1.1.1
-- remove an ip:

How to upgrade CoreOS manually

Before upgrading, make sure you are allowing insecure registry access, or your newer docker won't be able to talk to the Deis registry:

sudo bash -c 'mkdir -p /etc/systemd/system/docker.service.d/; cat <<EOF > /etc/systemd/system/docker.service.d/50-insecure-registry.conf
[Service]
Environment="DOCKER_OPTS=--insecure-registry 10.0.0.0/8 --insecure-registry 172.16.0.0/12 --insecure-registry 192.168.0.0/16"
EOF
