Installation of loklak with Docker

Installing loklak on Bluemix with Docker

  1. Install docker on your system

  2. Get a Bluemix Account with this URL: http://ibm.biz/joinbluemix
    2.1 Press Sigup and type in your credentials
    2.2 Check your email and press the validation link
    2.3 Sign in to bluemix

  3. Make sure you are in US South. The URL is https://console.ng.bluemix.net (beside US South there is London and Sydney)

  4. Press Dashboard and create a space called dev

  5. Install cloud foundry command line tools for your OS from here In Linux:

    dpkg -i cf-cli-version.dep

  6. Install ic plugin as described here Linux:

    cf install-plugin https://static-ice.ng.bluemix.net/ibm-containers-linux_x64

  7. Login to bluemix with

    cf login

    API endpoint is api.ng.bluemix.net

  8. Login to docker on bluemix with cf ic login (No credentials are necessary of you logged in to bluemix before

  9. Create namespace with

    cf ic namespace set <your namespace like hugo, make sure the name is unique>

root@44ee147e1aa5:/# cf ic namespace set hugo
FAILED
{
  "code": "IC5090E",
  "description": "Cannot assign namespace hugo to org 8b826387-9960-48d6-a409-1c5347b937af. Please ensure the namespace is not already in use.",
  "incident_id": "df24a7aedde48fbb",

}

root@44ee147e1aa5:/# cf ic namespace set ottohttps://codein.withgoogle.com/tasks/5485387342413824/
otto

  10. Init your docker connection with cf ic init

  11. Upload the loklak docker file to your namespace with cf ic cpi mariobehling/loklak loklak (takes some time)

  12. Create docker group with: (the XXXX must be unique, play around to found a free name)

cf ic group create --name loklak --auto --desired 2 -m 1024 -n XXXX -d mybluemix.net -p 80 registry.ng.bluemix.net/<namespace>/loklak
  1. Check if your group is running either with pressing Dashboard in the browser or:
cf ic group list
  1. Wait until your container group is build and the network is configured (>1 minute) and
check at https://XXXX.mybluemix.net is working with your version of loklak
  1. Send your own bluemix loklak link to Mario in order to prove your done it

Installing loklak on AWS with Docker

  1. Sign in to AWS

  2. In the top-right corner, choose a area you want to set up the instance, e.g.: Asia Pacific (Singapore).

  3. In the console panel, choose EC2. In EC2 Control Panel, choose key pairs, under Network & Security, and create a new key pair. It will automatically download the private key, and you should do chmod 400 YOUR_KEY_NAME to prevent other user to access your private key. After that, go back to your dashboard, and click Launch Instance.

  4. In Step 1: Choose an Amazon Machine Image, we choose Ubuntu Server 14.04 LTS (HVM), SSD Volume Type.

  5. In Step 2: Choose an Instance Type, we choose t2.micro(Warning: t2.micro is not suitable for running loklak for a long period, and AWS may shut down your instance(block your Internet access on specific port) at any time. t2.micro instance users are only allow to use 10% of a single CPU core on average. In our case, loklak_server uses 30 - 40% on average. Reference: Burstable Instance Case study: Real case running loklak)

  6. Then we click Configure Instance Details, do not create a instance yet.

  7. Under Auto-assign Public IP, we choose Enable

  8. Then we click Next: Add Storage

  9. We modify the storage to 30GiB instead of default 8Gib

  10. Click Next twice to go to Step 6: Configure Security Group. Under this, we choose All TCP for type and Anywhere for source.

  11. We are ready to launch, click Review and Launch, if everything is correct, click Launch. It will ask you to choose a key pair, choose the one we just created.

  12. We go back to EC2 control panel again. Click on instances on the left hand side. Then choose the instance you just created, and click connect button on top. It will you connect to your EC2 by giving you a example like:

    ssh -i "loklak.pem" ubuntu@ec2-54-169-103-75.ap-southeast-1.compute.amazonaws.com

  13. Once connected, we have to set up docker and add a 4G swapfile to prevent lack of memory:

    sudo apt-get update
sudo apt-get -y upgrade
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo apt-get install linux-image-extra-`uname -r`
sudo apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
echo "deb https://apt.dockerproject.org/repo ubuntu-trusty main" | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt-get update
sudo apt-get install docker-engine

  14. Once docker is installed, we start our loklak-server by entering:

    sudo docker pull mariobehling/loklak
sudo docker run -d -p 80:80 -p 443:443 mariobehling/loklak:latest

  15. Check if Loklak is running on your server, by going to your public DNS, e.g.: ec2-54-169-103-75.ap-southeast-1.compute.amazonaws.com.

Installing loklak on Google Cloud with Docker

  1. Go to Google Cloud Free Trial and sign up. You will get 300 dollars credit for 3 months.

  2. Go to the console page: Console

  3. If you don’t have any projects, a page that would guide you on how to start a project will pop up. Give your project a name.

  4. In the search bar above on console page, enter 'Compute Engine' and click on Compute Engine.

  5. If you have not activated billing for compute engine, click enable billing and choose your account to activate your Compute Engine. Your Google Compute Engine should be activated within a few minutes.

  6. Click Create instance to create an instance. In machine type, choose small(1 shared vCPU). Choose whatever zone you like.

    In Boot Disk, choose Ubuntu 14.04, and the disk size should be larger than 40GB. On the bottom of the page, click Management, disk, networking, access & security options to show more options. Inside of this, click into the tab Networking and choose New static IP instead of Ephemeral. Enter a name for your IP. Google will assign a IP for you. Check the two boxes Allow HTTP traffic and Allow HTTPS traffic. Finally, click Create to create an instance. Wait a few minutes for the creation to complete.

  7. Once the creation has finished, click ssh below to establish web ssh connections.

  8. In the Web Console, enter:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get -y install docker.io
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo docker build https://github.com/loklak/loklak_server.git

Once finished, the last line will provide the image ID, like Successfully built 4e11208a7b34. Copy or remember this id, we will need this id to tag the image. Tag your image by entering sudo docker tag YOUR_IMAGE_ID loklak. In my case, we enter sudo docker tag 4e11208a7b34 loklak Run our server by entering:

sudo docker run -d -p 80:80 -p 443:443 loklak

Enter your assigned IP address into your browser to check if it is working.

Installing loklak on DigitalOcean with Docker

DigitalOcean - simple cloud hosting, built for developers.

  1. Register in DigitalOcean and get 10$ credit.

  2. Click 'Create droplet' button, choose your droplet image (Docker), size, location and add your SSH keys.

    Droplet image

    SSH keys

  3. Click 'Create', wait a minute, copy ip of your new droplet and login to it using SSH:

    ssh root@YOUR.DROPLET.IP

  4. Docker is already installed, you can check it using docker version command. You should see something like this:

    root@sevazhidkov:~# docker version
Client:
 Version:      1.9.1

  5. Pull Docker image from Loklak repository in Docker Hub (it should take about a minute):

    docker pull mariobehling/loklak

  6. OK, you're ready to run Loklak:

    docker run -d -p 80:80 -p 443:443 mariobehling/loklak:latest

  7. Go to your droplet IP using web browser. You should see Loklak main page.
