Deckhouse Platform in a private environment
Caution! The settings for working through a proxy server have changed in Deckhouse 1.42 (issue). The guide is for Deckhouse 1.42+.
The recommended settings for a Deckhouse Platform Community Edition installation are generated below:
config.yml— a file with the configuration needed to bootstrap the cluster. Contains the installer parameters, access parameters, and the initial cluster parameters.
Please pay attention to:
- highlighted parameters you must define.
- parameters you might want to change.
- The installation must be performed from a personal computer with SSH access to the node, the master node of the future cluster.
Create the config.yml file.

Use a Docker image to install the Deckhouse Platform. It is necessary to transfer configuration files to the container as well as SSH keys for accessing the master node (further, it is assumed that the SSH key ~/.ssh/id_rsa is used).
Log in on the personal computer to the container image registry you specified in the previous step.
Run the installer on the personal computer.
docker run --pull=always -it -v "$PWD/config.yml:/config.yml" -v "$HOME/.ssh/:/tmp/.ssh/" <IMAGES_REPO_URI>/install:stable bash
docker run --pull=always -it -v "%cd%\config.yml:/config.yml" -v "%userprofile%\.ssh\:/tmp/.ssh/" <IMAGES_REPO_URI>/install:stable bash -c "chmod 400 /tmp/.ssh/id_rsa; bash"
Now, to initiate the process of installation, you need to execute inside the container:
dhctl bootstrap --ssh-user=<username> --ssh-host=<master_ip> --ssh-agent-private-keys=/tmp/.ssh/id_rsa \
--config=/config.yml \
--ask-become-pass
The --ssh-user parameter here refers to the user that generated the SSH key. If a password is required to run sudo on the server, then specify it in response to the request [sudo] Password:.
The installation process may take about 15-30 minutes with a good connection.
After the installation is complete, the installer will output the IP of the master node (you will need it further). Example output:
...
┌ 🎈 ~ Common: Kubernetes Master Node addresses for SSH
│ cloud-demo-master-0 | ssh ubuntu@1.2.3.4
└ 🎈 ~ Common: Kubernetes Master Node addresses for SSH (0.00 seconds)
Almost everything is ready for a fully-fledged Deckhouse Platform to work!
Use a Docker image to install the Deckhouse Platform. It is necessary to transfer configuration files to the container as well as SSH keys for accessing the master node (further, it is assumed that the SSH key ~/.ssh/id_rsa is used).
Log in on the personal computer to the container image registry you specified in the previous step.
Run the installer on the personal computer.
echo <LICENSE_TOKEN> | docker login -u license-token --password-stdin registry.deckhouse.io
docker run --pull=always -it -v "$PWD/config.yml:/config.yml" -v "$HOME/.ssh/:/tmp/.ssh/" registry.deckhouse.io/deckhouse/ee/install:stable bash
Log in on the personal computer to the container image registry by providing the license key as a password:
docker login -u license-token registry.deckhouse.io
Run a container with the installer:
docker run --pull=always -it -v "%cd%\config.yml:/config.yml" -v "%userprofile%\.ssh\:/tmp/.ssh/" registry.deckhouse.io/deckhouse/ee/install:stable bash -c "chmod 400 /tmp/.ssh/id_rsa; bash"
Now, to initiate the process of installation, you need to execute inside the container:
dhctl bootstrap --ssh-user=<username> --ssh-host=<master_ip> --ssh-agent-private-keys=/tmp/.ssh/id_rsa \
--config=/config.yml \
--ask-become-pass
The --ssh-user parameter here refers to the user that generated the SSH key. If a password is required to run sudo on the server, then specify it in response to the request [sudo] Password:.
The installation process may take about 15-30 minutes with a good connection.
After the installation is complete, the installer will output the IP of the master node (you will need it further). Example output:
