fetch_params

Get the names and values of parameters whose names begin with a given prefix. Uses aws ssm describe-parameters and get-parameters, to compile names and values into a convenient format.

Usage

• python set_param -p foo -v bar

  Creates a parameter named foo with value bar. By default, uses the SecureString parameter type

• python set_param -p foo -v bar -t String

  Creates a parameter named foo with value bar with type String. Valid types:

  • String
  • StringList
  • SecureString

• python set_param -p foo -v bang -o

  Overwrite foo's value to bang.

• python set_param -j parameters.json

  Create or update parameters from the file parameters.json containing parameter data in the format:

  [
     {
       "Name": "foo",
       "Value": "bar"
     },
     {
       "Name": "this",
       "Value": "that"
     }
   ]

  Type and Overwrite keys can also be included for each parameter. If omitted, these options default to SecureString and False.
