[英]AWS CLI: How to use variable to filter EFS
I want to use the value of the DOMAIN_ID
variable to filter the EFS to get a FileSystemId.我想使用DOMAIN_ID
变量的值来过滤 EFS 以获取 FileSystemId。 I used the commands below.我使用了下面的命令。 The first command works and it stores the domain ID.第一个命令有效,它存储域 ID。 The second one returns an empty list, even though the DOMAIN_ID
variable is present.第二个返回一个空列表,即使存在DOMAIN_ID
变量。
DOMAIN_ID=$(aws sagemaker list-domains --query 'Domains[0].DomainId')
aws efs describe-file-systems --query 'FileSystems[?CreationToken==`$DOMAIN_ID`].FileSystemId'
Output:输出:
[]
Expected output:预期输出:
<Some EFS identifier>
This works (escaping backticks) -这有效(转义反引号) -
aws efs describe-file-systems --query "FileSystems[?CreationToken==\`$DOMAIN_ID\`].FileSystemId"
You can also use describe-domain command instead -您也可以改用 describe-domain 命令 -
$ DOMAIN_ID=$(aws sagemaker list-domains --query 'Domains[0].DomainId' | tr -d '"')
$ aws sagemaker describe-domain --domain-id $DOMAIN_ID --query 'HomeEfsFileSystemId'
