  -h, --help                      help for nova-password
  -i, --private-key-path string   a path to the RSA private key (PuTTY and OpenSSH formats) (default "~/.ssh/id_rsa")

Prerequisites

Download and unzip the latest release for your operating system from the releases page.

• The private key corresponding to the public key used to create a compute instance is required.
• Only RSA PKCS #1 v1.5 is supported by OpenStack.
• OpenStack environment variables for authentication must be set. These are typically sourced from an openrc file, which includes credentials like your OpenStack username, project, and authentication endpoint. Without these environment variables, the tool will not be able to authenticate with OpenStack.

For reference, you can find simple examples of openrc files for Linux/macOS and Windows below:

• Example openrc.sh for Linux/macOS
• Example openrc.ps1 for Windows

TLS options

• OS_CACERT - environment variable with a path to a custom CA certificate.
• OS_INSECURE - skip endpoint TLS certificate validation. Set to true only if you are otherwise convinced of the OpenStack endpoint's authenticity.

Windows

Before using nova-password on Windows, make sure to source the OpenStack environment variables by running the openrc.ps1 script.

.\openrc.ps1
.\nova-password.exe --private-key-path C:\Users\user\key.pem my-server
# or
.\nova-password.exe 717433dc-4c2e-4d62-9467-6dd3715b2c6c server-name
# or
.\nova-password.exe my-server -i C:\Users\user\.ssh\putty.ppk

Linux / macOS

Before using nova-password on Linux or macOS, ensure that the OpenStack environment variables are sourced by running the openrc.sh script.

source ./openrc.sh
./nova-password --private-key-path ~/.ssh/id_rsa my-server
# or
./nova-password 717433dc-4c2e-4d62-9467-6dd3715b2c6c server-name
# or
./nova-password my-server -i ~/.ssh/putty.ppk
