From yesterday I'm in process of moving some of my services in new VPS which is based on latest Ubuntu LTS. Some of software that I'm using is "conterized" but not all of them. So moving to new VPS is time to fix that and Redis is first in my list. After quick research I figure out that I preffer to use Phusion base image for Redis also, instead of getting new images :) and because of that I update a little bit original Docker file to: 
# Pull base image.
FROM phusion/baseimage:0.9.19

# Install Redis.
RUN \
    cd /tmp && \
    apt-get update && \
    apt-get install wget -y && \
    apt-get install make -y && \
    apt-get install gcc -y && \
    wget http://download.redis.io/redis-stable.tar.gz && \
    tar xvzf redis-stable.tar.gz && \
    cd redis-stable && \
    make && \
    make install && \
    cp -f src/redis-sentinel /usr/local/bin && \
    mkdir -p /etc/redis && \
    cp -f *.conf /etc/redis && \
    rm -rf /tmp/redis-stable* && \
    sed -i 's/^\(bind .*\)$/# \1/' /etc/redis/redis.conf && \
    sed -i 's/^\(daemonize .*\)$/# \1/' /etc/redis/redis.conf && \
    sed -i 's/^\(dir .*\)$/# \1\ndir \/data/' /etc/redis/redis.conf && \
    sed -i 's/^\(logfile .*\)$/# \1/' /etc/redis/redis.conf

# Define mountable directories.
VOLUME ["/data"]

# Define working directory.
WORKDIR /data

# Define default command.
CMD ["redis-server", "/etc/redis/redis.conf"]

# Expose ports.
EXPOSE 6379
So we can save this in some directory in 
Dockerfile
after that we can user 
docker build -t="dockerfile/redis" .
Result will something like: 
root@sylvester:/tmp/tt# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED          SIZE
dockerfile/redis    latest              fd12d74a4a9d        21 minutes ago   382.2 MB
phusion/baseimage   0.9.19              c39664f3d4e5        4 weeks ago      225.6 MB
That is :) we can quickly use it with something like 
docker run -d --name redis -p 6379:6379 dockerfile/redis redis-server --requirepass <password>
Result will be: 
root@sylvester:/tmp/tt# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
7efeb6befa28        dockerfile/redis    "redis-server --requi"   11 minutes ago      Up 11 minutes       0.0.0.0:6379->6379/tcp   redis
And woala we have fully functional Redis instance.
Happy codding
