Upgrade Linux infrastructure

Last updated on

Run the commands on the VM where the Linux chaos infrastructure is installed. The path differs between SaaS and self-managed platform (SMP).

SaaS​

  1. Fetch INFRA_ID and ACCESS_KEY from the existing config:

    INFRA_ID=$(sed -n 's/^infraID: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)
    ACCESS_KEY=$(sed -n 's/^accessKey: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)

  2. Uninstall the current version:

    /etc/linux-chaos-infrastructure/uninstall.sh

  3. Install the new version. Get the binary URL from the Linux infrastructure page in the Harness UI, then run:

    sudo https://app.harness.io/public/shared/tools/chaos/linux/1.50.0/install.sh \
      | bash /dev/stdin \
        --infra-id "$INFRA_ID" \
        --access-key "$ACCESS_KEY" \
        --server-url https://<YOUR_IP>/chaos/lserver/api

    Replace 1.50.0 with the target version and <YOUR_IP> with your cluster address.

SMP​

  1. Raise a Harness support ticket to get the offline-linux-installer tarball.

  2. Copy and extract the tarball on the target VM, then cd into the extracted directory.

  3. Fetch INFRA_ID and ACCESS_KEY from the existing config:

    INFRA_ID=$(sed -n 's/^infraID: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)
    ACCESS_KEY=$(sed -n 's/^accessKey: "\(.*\)"/\1/p' /etc/linux-chaos-infrastructure/config.yaml)

  4. Uninstall the current version with /etc/linux-chaos-infrastructure/uninstall.sh.

  5. Install the new version:

    sudo ./install.sh \
      --infra-id "$INFRA_ID" \
      --access-key "$ACCESS_KEY" \
      --server-url https://<YOUR_IP>/chaos/lserver/api

This same command works in air-gapped environments once the installer is on the VM.
