Previously, I have used the discourse packages from https://packager.io/gh/pkgr/discourse because that was easy to install and to maintain, just with Ubuntu packages.

Unfortunately, those packages have not been updated for a while.

Another thing is that I can now run docker within an lxc container, which makes it easier for me to deploy docker on my root server.

So I decided to upgrade my pkgr discourse installation from 1.5.1 to the latest stable docker discourse installation.

These threads and pages have helped me:

• https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md
• https://meta.discourse.org/t/install-discourse-at-lower-version/22446/5
• https://meta.discourse.org/t/change-tracking-branch-for-your-discourse-instance/17014

So I created a backup of the 1.5.1 installation, within the admin dashboard, and downloaded that locally.

I created an LXC container with Fedora 24 (see https://github.com/tpokorra/lxc-scripts/issues/27).

Inside the container:

dnf install docker git which
systemctl enable docker
systemctl start docker
mkdir /var/discourse
git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
# comment last line, because we want to edit the file containers/app.yml before installing
sed -i 's~./launcher bootstrap~#./launcher bootstrap~g' discourse-setup
./discourse-setup
# edit containers/app.yml:
#   comment the line with 443:443 because I am using nginx outside of the LXC container for https
#   in section params, add this line:
#     version: v1.5.1
#   I changed UNICORN-WORKERS from 6 to 2, because my forum does not have much traffic
./launcher bootstrap app && ./launcher start app

Now I login to the new discourse installation, with the admin email address specified in discourse-setup. Checking in the dashboard, I have version 1.5.1 indeed.

I restore the backup that I downloaded from the old server (need to make sure to enable restore first in the dashboard settings!).

Verify that the forum works.

Now upgrade Discourse to the latest stable version:

cd /var/discourse
git pull
sed -i "s/^  version:.*/  version: stable/g" containers/app.yml
./launcher rebuild app

For the LightBuildServer (LBS) I want to run some of my nightly builds already against Fedora 25 Beta, to see if I need to fix anything in the Mono packages for Fedora.

But there is no Beta image for Fedora 25 available at Docker Hub: https://hub.docker.com/_/fedora/

But here you can find an image for Fedora 25 Beta: https://getfedora.org/fi/cloud/prerelease/docker.html

So I download the image, and load the image like this:

cd /var/lib/docker
wget https://download.fedoraproject.org/pub/fedora/linux/releases/test/25_Beta/Docker/x86_64/images/Fedora-Docker-Base-25_Beta-1.1.x86_64.tar.xz
docker load -i /var/lib/docker/Fedora-Docker-Base-25_Beta-1.1.x86_64.tar.xz

You can see the image listed, when typing docker images:

REPOSITORY                                 TAG                 IMAGE ID            CREATED             SIZE
fedora-docker-base-25_beta-1.1.x86_64      latest              a85629813141        8 days ago          197.8 MB

Now I can reference it in my Dockerfile like this:

FROM fedora-docker-base-25_beta-1.1.x86_64:latest

Make sure to use the image name in lower case.

This describes how to install a docker image of Kolab.

Please note: this is not meant to be for production use. The main purpose is to provide an easy way for demonstration of features and for product validation.

This installation has not been tested a lot, and could still use some fine tuning. This is just a demonstration of what could be done with Docker for Kolab.

Preparing for Docker
I am using a Jiffybox provided by DomainFactory for downloading a Docker container for Kolab 3.4 running on CentOS 7.

I have installed Fedora 21 on a Jiffybox.

Now install docker:

sudo yum install docker-io
systemctl start docker
systemctl enable docker

Install container
The image for the container is available here:
https://registry.hub.docker.com/u/tpokorra/kolab34_centos7/
If you want to know how this image was created, read my other blog post http://www.pokorra.de/2015/06/building-a-docker-container-for-kolab-3-4-on-jiffybox/.

To install this image, you need to type in this command:

docker pull tpokorra/kolab34_centos7

You can create a container from this image and run it:

MYAPP=$(sudo docker run --name centos7_kolab34 -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 443:443 -h kolab34.test.example.org -d -t -i tpokorra/kolab34_centos7 /bin/bash)

You can see all your containers:

docker ps -a

You should attach to the container, and inside the container change the root password:

docker attach $MYAPP
  # you might need to press Enter to see the login screen
  # login with user root and password root
  # enter a secure password:
  passwd root

To stop the container:

docker stop $MYAPP

To delete the container:

docker rm $MYAPP

You can reach the Kolab Webadmin on this URL (replace localhost with the IP address of the Jiffybox):
https://localhost/kolab-webadmin. Login with user: cn=Directory Manager, password: test

The Webmail interface is available here:
https://localhost/roundcubemail.

This article is an update of the previous post that built a Docker container for Kolab 3.3 from September 2014.

Preparation
I am using a Jiffybox provided by DomainFactory for building the Docker container.

I have installed Fedora 21 on a Jiffybox.

Now install docker:

sudo yum install docker-io
systemctl start docker
systemctl enable docker

Create a Docker image

To learn more about Dockerfiles, see the Dockerfile Reference

My Dockerfile is available on Github: https://github.com/TBits/KolabScripts/blob/Kolab3.4/kolab/Dockerfile. You should store it with filename Dockerfile in your current directory.

This command will build a container with the instructions from the Dockerfile in the current directory. When the instructions have been successful, an image with the name tpokorra/kolab34_centos7 will be created, and the container will be deleted:

sudo docker build -t tpokorra/kolab34_centos7 .

You can see all your local images with this command:

sudo docker images

To finish the container, we need to run setup-kolab, this time we define a hostname as a parameter:

MYAPP=$(sudo docker run --name centos7_kolab34 -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 443:443 -h kolab34.test.example.org -d -t -i tpokorra/kolab34_centos7 /bin/bash)
docker attach $MYAPP
# you might need to press the Enter key to see the login prompt...
# login with user root and password root
# run inside the container:
echo 2 | setup-kolab --default --timezone=Europe/Brussels --directory-manager-pwd=test
cd /root/KolabScripts-Kolab3.4/kolab
./initHttpTunnel.sh
./initSSL.sh test.example.org
shutdown -h now

Now you commit this last manual change:

docker commit $MYAPP tpokorra/kolab34_centos7
# delete the container
docker rm $MYAPP

You can push this image to https://registry.hub.docker.com:

#create a new account, or login with existing account:
sudo docker login
# there is currently an issue with the Fedora 21 rpm package (docker-io-1.6.0-4.git350a636.fc21.x86_64)
# see also https://forums.docker.com/t/docker-push-error-fata-0001-respository-does-not-exist/1309/18
# solution: yum install --enablerepo=updates-testing docker-io
sudo docker push tpokorra/kolab34_centos7

You can now see the image available here: https://registry.hub.docker.com/u/tpokorra/kolab34_centos7/

See this post Installing Demo Version of Kolab 3.4 with Docker about how to install this image on the same or a different machine, for demo and validation purposes.

Current status: There are still some things not working fine, and I have not tested everything.
But this should be a good starting point for other people as well, to help with a good demo installation of Kolab on Docker.

Preparing for Docker
I am using a Jiffybox provided by DomainFactory for downloading a Docker container for Kolab 3.3 running on CentOS 6.

I have installed Ubuntu 12.04 LTS on a Jiffybox.
I am therefore following Docker Installation instructions for Ubuntu for the installation instructions:

Install a kernel that is required by Docker:

sudo apt-get update
sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring

After that, in the admin website of JiffyBox, select the custom kernel Bootmanager 64 Bit (pvgrub64); see also the german JiffyBox FAQ. Then restart your JiffyBox.

After the restart, uname -a should show something like:

Linux j89610.servers.jiffybox.net 3.8.0-37-generic #53~precise1-Ubuntu SMP Wed Feb 19 21:37:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Now install docker:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
 
sudo sh -c "echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
 
sudo apt-get update
sudo apt-get install lxc-docker

Install container
The image for the container is available here:
https://index.docker.io/u/tpokorra/kolab33_centos6/
If you want to know how this image was created, read my other blog post http://www.pokorra.de/2014/09/building-a-docker-container-for-kolab-3-3-on-jiffybox/.

To install this image, you need to type in this command:

docker pull  tpokorra/kolab33_centos6

You can create a container from this image and run it:

MYAPP=$(sudo docker run --name centos6_kolab33 -P -h kolab33.test.example.org -d -t -i tpokorra/kolab33_centos6)

You can see all your containers:

docker ps -a

You now have to attach to the container, and inside the container start the services:

docker attach $MYAPP
  /root/start.sh

Somehow it should work to start the services automatically at startup, but I did not get it to work with CMD or ENTRYPOINT.

To stop the container, type exit on the container’s console, or run from outside:

docker stop $MYAPP

To delete the container:

docker rm $MYAPP

You can reach the Kolab Webadmin on this URL:

sudo sh -c "echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
 
sudo apt-get update
sudo apt-get install lxc-docker

Create a Docker image
I realised that if I would install Kolab in one go, the image would become too big to upload to https://index.docker.io.
Therefore I have created a Dockerfile which has several steps for downloading and installing various packages. For a detailed description of a Dockerfile, see the Dockerfile Reference

My Dockerfile is available on Github: https://github.com/TBits/KolabScripts/blob/Kolab3.3/kolab/Dockerfile. You should store it with filename Dockerfile in your current directory.

To finish the container, we need to run setup-kolab, this time we define a hostname as a parameter:

MYAPP=$(sudo docker run --name centos6_kolab33  --privileged=true -h kolab33.test.example.org -d -t -i tpokorra/kolab33_centos6 /bin/bash)
docker attach $MYAPP
# run inside the container:
  echo `hostname -f` > /proc/sys/kernel/hostname
  echo 2 | setup-kolab --default --timezone=Europe/Brussels --directory-manager-pwd=test
  ./initHttpTunnel.sh
  ./initSSL.sh test.example.org
  /root/stop.sh
  exit

Typing exit inside the container will stop the container.

Now you commit this last manual change:

docker commit $MYAPP tpokorra/kolab33_centos6
# delete the container
docker rm $MYAPP

You can push this image to https://index.docker.io:

#create a new account, or login with existing account:

(-P should work instead of -p 443:443 and use the ports defined by EXPOSE in Dockerfile, but that does not work for me at the moment…)

You can see all your containers:

docker ps -a

You now have to attach to the container, and inside the container start the services:

Therefore I have created a Dockerfile which has several steps for downloading and installing various packages. For a detailed description of a Dockerfile, see the Dockerfile Reference

My Dockerfile looks like this:

FROM centos
RUN mv /etc/localtime /etc/localtime.old; ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime
RUN echo "NAME=kolab31.test.example.org" > /etc/sysconfig/network; echo "kolab31.test.example.org" > /proc/sys/kernel/hostname

# allow connections on port 443 (https)
EXPOSE 443
# TODO: allow IMAP as well
 
#CMD ["/sbin/init"]

This command will build a container with the instructions from the Dockerfile in the current directory. When the instructions have been successful, an image with the name tpokorra/kolab31_centos6 will be created, and the container will be deleted:

sudo docker build -t tpokorra/kolab31_centos6 .

You can see all your local images with this command:

sudo docker images

To finish the container, we need to run setup-kolab, this time we define a hostname as a parameter:

MYAPP=$(sudo docker run --name centos6_kolab31 -h kolab31.test.example.org -d -t -i tpokorra/kolab31_centos6 /bin/bash)
docker attach $MYAPP
# run inside the container:
  echo `hostname -f` > /proc/sys/kernel/hostname
  setup-kolab --default --timezone=Europe/Brussels --directory-manager-pwd=test
  ./initSSL.sh
  cat > /root/start.sh << EOF
#!/bin/bash
service httpd start
service mysqld start
service dirsrv start
service cyrus-imapd start

EOF
  chmod a+x /root/start.sh
  service kolabd stop
  service dirsrv stop
  service cyrus-imapd stop
  service mysqld stop
  service httpd stop
  exit

Typing exit inside the container will stop the container.

Now you commit this last manual change:

docker commit $MYAPP tpokorra/kolab31_centos6
# delete the container
docker rm $MYAPP

You can push this image to https://index.docker.io:

#create a new account, or login with existing account:

sudo docker push tpokorra/kolab31_centos6

You can now see the image available here: https://index.docker.io/u/tpokorra/kolab31_centos6/
