AWS Parameter Store (SSM)

#aws ssm put-parameter --name "test123" --type "String" --value "MyValue"
#{
#  "Version": 1,
#  "Tier": "Standard"
#}

Note:- If the Value contains a URL, it will create an error:-

$ aws ssm put-parameter --name "/repo/testpar3" --value "https://server/repo3.git" --description "repo_backup" --type "String"

Error parsing parameter '--value': Unable to retrieve https://server/repo3.git: Could not connect to the endpoint URL: "https://server/repo3.git"

Fix is to use:-

$ aws configure set cli_follow_urlparam false

$ aws ssm put-parameter --name "/repo/testpar3" --value "https://server/repo3.git" --description "repo_backup" --type "String"
{
    "Version": 1,
    "Tier": "Standard"
}

$ aws ssm get-parameters --names "/ami/AMZN2/latest" --query "Parameters[*].{Value:Value}" --profile nonprod
[
    {
        "Value": "ami-05432161ea123456"
    }
]
$

This uses an option to pattern match:-

$ cat parameters.sh
#!/bin/bash
# Get the Name output from command, this requires 
# export AWS_DEFAULT_OUTPUT="json", text as an output clearly won't work with ''jq''

export AWS_DEFAULT_OUTPUT="json"
aws ssm describe-parameters --parameter-filters "Key=Name, Values=/repo/testpar, Option=Contains" | jq '.[] | .[].Name'


$ ./parameters.sh
"/repo/testpar1"
"/repo/testpar2"
"/repo/testpar3"
