Deploy Confluent Platform in Air-Gapped Environment Using Ansible Playbooks

This topic guides you through the steps to use Ansible Playbooks to deploy Confluent Platform without internet connectivity to outside networks.

This scenario requires:

  • A distribution server with internet connectivity

    You download the Ansible Playbooks for Confluent Platform (Confluent Ansible) collection and the Confluent Platform packages from the Confluent site to your distribution server.

    You need to install ansible-galaxy on the distribution server.

  • A control node to run Ansible

    This internal repository should be accessible from your Confluent Platform hosts and the distribution server.

  • Internal hosts to run Confluent Platform.

    The Confluent Platform hosts must be able to reach the control node at port 8080.

At the high level, the required steps are:

  1. Download the Confluent Platform packages and other required files, such as monitoring JARs, Confluent CLI, and the Cryptography pip package, along with Ansible collections. (This step requires internet connectivity.)
  2. Put the packages and other required files that you downloaded in the previous step on your repository server.
  3. Configure the variables for Ansible to use an internal custom repository server for Confluent Platform installation.
  4. Install Confluent Platform.

Deploy using tarball archives

Step 1: Distribute Confluent Ansible collection

Build the Confluent Ansible collection and install the collection on the control node.

  1. Create a directory with the following structure on the distribution server:

    mkdir -p <path_to_cp-ansible>/ansible_collections/confluent/

    You can put <path_to_cp-ansible> anywhere in your directory structure, but the directory structure under <path_to_cp-ansible> should be set up exactly as specified above.

  2. Clone the Ansible Playbooks for Confluent Platform repo into the platform directory inside the directory you created in the previous step:

    git clone https://github.com/confluentinc/cp-ansible \
  <path_to_cp-ansible>/ansible_collections/confluent/platform

  3. Check out the 7.8.0-post branch:

    cd <path_to_cp-ansible>/ansible_collections/confluent/platform
git fetch
git checkout 7.8.0-post

  4. Create the collection:

    ansible-galaxy collection build

    The command builds a tarball of the collection in the current directory.

  5. Upload the collection tarball to your control node:

    scp <collection tarball> <control-node>:/path/to/confluent-collection

  6. Install the collection on the control node:

    ansible-galaxy collection install /path/to/confluent-collection/<collection tarball>

    For more information about Ansible collection distribution, see Building your collection tarball.

  7. Download and install the cryptography pip package.

    1. Download the cryptography pip package to the distribution server:

      pip download cryptography -d <local directory on distribution server>

    2. Transfer the cryptography package to all the Confluent Platform hosts (managed nodes):

      scp <local directory on distribution server> <managed-node>:/<some-path-on-managed-node-to-keep-pip-packages>

    3. Install the cryptography package:

      cd <some-path-on-managed-node-to-keep-pip-packages>
pip install <crpyptography-wheel-file-name> -f ./ --no-index
      • -f argument takes in the local path of directory where .whl files are present.
      • --no-index is for ignoring the remote repo and only looking inside the current directory.

Step 2: Download Confluent Platform archives

  1. Download the Confluent Platform archives to the distribution server:

    curl -O http://packages.confluent.io/archive/7.8/confluent-7.8.0.tar.gz

    If enabling monitoring, download the required JARs:

    curl -o /tmp/confluent-packages/jolokia-jvm-1.6.2-agent.jar \
  http://search.maven.org/remotecontent?filepath=org/jolokia/jolokia-jvm/1.6.2/jolokia-jvm-1.6.2-agent.jar

    curl -o /tmp/confluent-packages/jmx_prometheus_javaagent-0.12.0.jar \
  https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.12.0/jmx_prometheus_javaagent-0.12.0.jar

  2. Move the packages and files to the control node:

    scp confluent-packages.tar.gz <control-node>:/path/to/confluent-packages.tar.gz

  3. On the control node, extract the contents of the Confluent Platform archive:

    tar xzf confluent-7.8.0.tar.gz

Step 3: Install Confluent Ansible

  1. Configure Confluent Ansible as described in Configure Ansible Playbooks for Confluent Platform.

  2. Add the following in the Ansible inventory file.

    • To install Confluent Platform using a tarball hosted on a web server:

      all:
  vars:
    repository_configuration: custom
    installation_method: archive
    confluent_archive_file_source: <web server url>/path/to/confluent-7.8.0.tar.gz

    • To install Confluent Platform using a tarball placed on the control node:

      all:
  vars:
    installation_method: archive
    confluent_archive_file_source: /path/to/confluent-7.8.0.tar.gz
    confluent_archive_file_remote: false

  3. Configure monitoring in the Ansible inventory file:

    • To enable Jolokia:

      jolokia_enabled: true
jolokia_url_remote: false
jolokia_jar_url: /path/to/jolokia-jvm-1.6.2-agent.jar

    • To enable JMX exporter:

      jmxexporter_enabled: true
jmxexporter_url_remote: false
jmxexporter_jar_url: /path/to/jmx_prometheus_javaagent-0.12.0.jar

  4. Install Confluent Ansible as described in the Installation Guide.

pip install <crpyptography-wheel-file-name> -f ./ --no-index
      • -f argument takes in the local path of directory where .whl files are present.
      • --no-index is for ignoring the remote repo and only looking inside the current directory.

Step 2: Download Confluent Platform packages

On the distribution server:

  1. Install the epel-release package:

    yum -y install epel-release

  2. Create the confluent.repo file for pulling the Confluent Platform packages:

    echo "[Confluent.dist]
baseurl = https://packages.confluent.io/rpm/7.8
enabled = 1
gpgcheck = 1
gpgkey = https://packages.confluent.io/rpm/7.8/archive.key
name = Confluent repository (dist)

[Confluent]
baseurl = https://packages.confluent.io/rpm/7.8
enabled = 1
gpgcheck = 1
gpgkey = https://packages.confluent.io/rpm/7.8/archive.key
name = Confluent repository" \
> /etc/yum.repos.d/confluent.repo

  3. Create a directory and download the Confluent Platform packages into that directory:

    mkdir /tmp/confluent-packages/

    yum clean all

yum install --downloadonly --downloaddir=/tmp/confluent-packages/ \
  confluent-platform \
  confluent-security \

  https://repo1.maven.org/maven2/io/prometheus/jmx/jmx_prometheus_javaagent/0.12.0/jmx_prometheus_javaagent-0.12.0.jar

Step 3: Host Confluent Platform packages on control node

Copy the Confluent Platform packages to the control node and run a simple repository server over a Python web server.

  1. On the distribution server, package and move the the files to the control node:

    cd /tmp

tar -zcvf confluent-packages.tar.gz confluent-packages

scp /tmp/confluent-packages.tar.gz <control-node>:/tmp/confluent-packages.tar.gz

  2. On the control node, decompress and install the packages:

    cd /tmp
tar xvzf confluent-packages.tar.gz -C /tmp

    cd /tmp/confluent-packages/
yum -y localinstall createrepo-*.rpm

  3. Create a repo, and host the control node with python3 http.server:

    createrepo .

    python3 -m http.server 8080

Step 4: Install Confluent Ansible

Install Ansible on the control node, create a repo file for the rest of the Confluent Platform hosts to use, and install Confluent Platform.

  1. On the control node, install Confluent Ansible:

    cd /tmp/confluent-packages/
yum -y localinstall ansible-*.rpm

  2. On the control node, create a .repo file that each host will use. If your organization has a repository server, that file should be configured for the existing repository server.

    echo "[confluent-repo]
name=Confluent Repo
baseurl=http://<ansible-control-node>:8080
enabled=1
gpgcheck=0" \
> /tmp/confluent.repo

  3. Configure Confluent Ansible as described in Configure Ansible Playbooks for Confluent Platform, and add the following in the Ansible inventory file:

    all:
  vars:
    repository_configuration: custom
    custom_yum_repofile_filepath: /tmp/confluent.repo

  4. Configure monitoring in the Ansible inventory file:
