Install Kontena Platform
NOTE! This documentation is for those who want to use the Kontena open source project to deploy custom Kontena Platform. Use of Kontena Cloud is optional. If you don't want to tinker and maintain Kontena Platform yourself, please see quick start documentation instead.
Step 1. Install Kontena CLI (command-line interface)
$ brew install kontena
Linux / Windows
Prerequisites: You'll need Ruby version 2.1 or later installed on your system. For more details, see the official Ruby installation docs.
You can install the Kontena CLI using the Rubygems package manager (which is included in Ruby).
$ gem install kontena-cli
After the installation is complete, you can test the installation by checking the Kontena CLI version with
To enable tab-completion for bash, add this to your
which kontena > /dev/null && . "$( kontena whoami --bash-completion-path )"
Step 2. Install Kontena Platform Master
In order to use Kontena, you'll need a Kontena Platform Master. A Kontena Platform Master may be provisioned on any cloud infrastructure. It's also possible to install Kontena Platform Master on your own machine for testing purposes.
During the Kontena Platform Master installation process, you will have to choose how users will be authenticated. While it is possible to use any OAuth2 authentication provider, we recommended using Kontena Cloud as the authentication provider. Learn more about the Kontena Platform Master authentication.
Step 3. Install Kontena Nodes
Once Kontena Platform Master is up and running, you'll need some Kontena Nodes to run your containerized workloads. Before Kontena Nodes may be added, Kontena Platform Grid must be defined. Each custom Kontena Platform Master installation comes with a pre-created Grid called 'test'. If you want to create or switch to another Grid, you can do it by using:
$ kontena grid create <NAME_OF_THE_GRID> # or to switch to an existing grid, use: $ kontena grid use <NAME_OF_THE_GRID> # to list all the grids, type: $ kontena grid list
Once you have Kontena Platform Grid setup, you can add Kontena Nodes.
If you followed the steps above, you should now have a working Kontena setup installed. Verify the setup using the
kontena node list command. It should list all the Kontena Nodes in your Grid.
$ kontena node list
Step 4. Deploy Your First Kontena Stack
Now you are ready to deploy your first Kontena Stack. In this section we will show you how to package a simple WordPress application and deploy it to your Kontena Platform.
First create the
kontena.yml file with the following contents:
stack: examples/wordpress version: 0.3.0 variables: wordpress-mysql-root: type: string from: vault: wordpress-mysql-root random_string: 32 to: vault: wordpress-mysql-root wordpress-mysql-password: type: string from: vault: wordpress-mysql-password random_string: 32 to: vault: wordpress-mysql-password services: wordpress: image: wordpress:4.6 stateful: true ports: - 80:80 environment: WORDPRESS_DB_HOST: mysql WORDPRESS_DB_USER: wordpress WORDPRESS_DB_NAME: wordpress secrets: - secret: wordpress-mysql-password name: WORDPRESS_DB_PASSWORD type: env mysql: image: mariadb:5.5 stateful: true environment: MYSQL_DATABASE: wordpress MYSQL_USER: wordpress secrets: - secret: wordpress-mysql-root name: MYSQL_ROOT_PASSWORD type: env - secret: wordpress-mysql-password name: MYSQL_PASSWORD type: env
You can then install and deploy the
$ kontena stack install kontena.yml [done] Creating stack wordpress [done] Deploying stack wordpress
The initial stack deployment may take some time while the host nodes pull the referenced Docker images.
After the stack deployment is finished you can verify that the wordpress and mysql services are running:
$ kontena stack ls NAME VERSION SERVICES STATE EXPOSED PORTS ⊝ wordpress 0.3.0 2 running *:80->80/tcp
You can use the
kontena stack commands to view the resulting configuration of each deployed stack service:
$ kontena service show wordpress/wordpress test/wordpress/wordpress: stack: test/wordpress status: running image: wordpress:4.6 revision: 2 stateful: yes scaling: 1 strategy: ha deploy_opts: min_health: 0.8 dns: wordpress.wordpress.test.kontena.local secrets: - secret: wordpress-mysql-password name: WORDPRESS_DB_PASSWORD type: env env: - WORDPRESS_DB_HOST=mysql - WORDPRESS_DB_USER=wordpress - WORDPRESS_DB_NAME=wordpress net: bridge ports: - 80:80/tcp instances: wordpress-wordpress-1: rev: 2016-11-28 13:51:02 UTC service_rev: 2 node: hidden-moon-99 dns: wordpress-1.wordpress.test.kontena.local ip: 10.81.128.115 public ip: 192.0.2.1 status: running exit code: 0
To test the wordpress service, you must connect to the IP address of the host node publishing the wordpress service on TCP port 80.
You can use the public IP address of the host node running the service instance displayed as part of the
kontena service show output.
Note: For the special case of using Vagrant for the Kontena setup, you must use the private IP address of the node running the
kontena node show hidden-moon-99 | grep 'private ip'.
