Login to docker registry with client certificate under windows
To login to a Docker registry using a client certificate on Windows, you can follow these steps:
Generate or obtain a client certificate: If you don't already have a client certificate, you'll need to generate or obtain one. This typically involves creating a private key and a corresponding certificate signing request (CSR) and then getting the certificate signed by a certificate authority (CA). Alternatively, you may receive a client certificate from a CA or an organization.
Install the client certificate: Install the client certificate into your Windows certificate store. You can do this by double-clicking the certificate file (.pfx or .p12) and following the certificate import wizard. Make sure to select the appropriate certificate store, such as "Current User" or "Local Machine", based on your requirements.
Open PowerShell or Command Prompt: Open a PowerShell or Command Prompt window with administrative privileges. This is necessary to run the Docker commands as an administrator.
Export client certificate as .pem files: Convert the client certificate and private key into separate .pem files. To do this, you can use OpenSSL or other certificate management tools. Run the following command in the PowerShell or Command Prompt window:
shellopenssl pkcs12 -in <path_to_certificate.pfx> -out <path_to_certificate.pem> -clcerts -nokeys
openssl pkcs12 -in <path_to_certificate.pfx> -out <path_to_key.pem> -nocerts -nodes
Replace
<path_to_certificate.pfx>
with the path to your client certificate file, and<path_to_certificate.pem>
and<path_to_key.pem>
with the desired paths for the exported .pem files.Set environment variables: Set the environment variables required for Docker to recognize and use the client certificate. In the PowerShell or Command Prompt window, run the following commands:
shellsetx DOCKER_TLS_VERIFY "1"
setx DOCKER_CERT_PATH "<path_to_directory_containing_pem_files>"
Replace
<path_to_directory_containing_pem_files>
with the path to the directory containing the exported .pem files.Login to the Docker registry: Finally, use the
docker login
command to authenticate with the Docker registry. Run the following command and provide the appropriate registry URL:shelldocker login <registry_url>
Docker will recognize the environment variables and use the client certificate for authentication when connecting to the registry.
With these steps, you should be able to login to a Docker registry using a client certificate on Windows. Make sure to adapt the commands and paths based on your specific environment and requirements.
