AWS::ECS::TaskDefinition EnvironmentFile
A list of files containing the environment variables to pass to a container. You can
specify up to ten environment files. The file must have a .env
file
extension. Each line in an environment file should contain an environment variable
in
VARIABLE=VALUE
format. Lines beginning with #
are treated
as comments and are ignored. For more information on the environment variable file
syntax, see Declare default
environment variables in file
If there are environment variables specified using the environment
parameter in a container definition, they take precedence over the variables contained
within an environment file. If multiple environment files are specified that contain
the
same variable, they are processed from the top down. It is recommended to use unique
variable names. For more information, see Specifying Environment
Variables in the Amazon Elastic Container Service Developer Guide.
This field is not valid for containers in tasks using the Fargate launch type.
