AWS Tools for Windows PowerShell
Command Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Synopsis

Obtains time-limited authorization tokens for one or more Amazon EC2 Container Registries and outputs a PSObject containing the login user credentials, endpoint data and a pre-formatted login command for your default registry. If one or more registry IDs are specified, multiple objects are output containing the login details for each registry.

Syntax

Get-ECRLoginCommand
-RegistryId <String[]>

Description

Retrieves a token that is valid for a specified registry for 12 hours and outputs a PSObject containing the decoded username, password, proxy endpoint and token expiry data, plus a pre-formatted docker login command utilizing those fields that you can execute to log in to your registry with Docker. After you have logged in to an Amazon ECR registry with this command, you can use the Docker CLI to push and pull images from that registry until the token expires. The credentials and region required to call the service to obtain the authorization token(s) can be specified using parameters to the cmdlet or will be obtained from the shell-default user credential profile and region.

NOTE: This command writes objects to the pipeline containing authentication credentials. Your credentials could be visible by other users on your system in a process list display or a command history. If you are not on a secure system, you should consider this risk and login interactively. For more information, see GetAuthorizationToken and What Is Amazon EC2 Container Registry?in the Amazon EC2 Container Registry documentation.

Parameters

-RegistryId <String[]>
Optional collection of one or more AWS account IDs associated with the registries for which to get authorization tokens and login commands. If you do not specify any IDs, a single login command for your default registry is output.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String[] object to this cmdlet for the RegistryId parameter.

Outputs

PSObject[]
This cmdlet returns one or more PSOBjects containing the login data and pre-formatted login command(s) to your registries.

Examples

Example 1

PS C:\> Get-ECRLoginCommand

Username : AWS
Password : eyJwYXlsb2Fk...kRBVEFfS0VZIn0=
ProxyEndpoint : https://123456789012.dkr.ecr.us-west-2.amazonaws.com
Endpoint : https://123456789012.dkr.ecr.us-west-2.amazonaws.com
ExpiresAt : 9/26/2017 6:08:23 AM
Command : docker login --username AWS --password eyJwYXlsb2Fk...kRBVEFfS0VZIn0= https://123456789012.dkr.ecr.us-west-2.amazonaws.com
Returns a PSObject containing login information for your default registry. The AWS credentials and region endpoint required for the call to obtain the authorization token are obtained from the shell defaults (set up by the Set-AWSCredential/Set-DefaultAWSRegion or Initialize-AWSDefaultConfiguration cmdlets). You can use the Command property with Invoke-Expression to log in to the specified registry or use the returned credentials in other tools requiring login.

Example 2

PS C:\>Get-ECRLoginCommand -ProfileName myprofile -Region us-east-1
Returns login information for your default registry using the specified region and AWS credentials from the specified credential profile to obtain the authorization token.

Example 3

PS C:\> Get-ECRLoginCommand -RegistryId "123456789012","210987654321"

Returns login information for multiple registries, one PSObject per specified registry ID.
