file .env with docker secret

[adouren]

Hello,

I put the passwords of an elastic stack in a ".env" file.

File .env:

ELASTIC_PASSWORD=elastic

…

elasticsearch: image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3 env_file:

.env …

When executing the stack, it works very well and the environment variables are updated in the stack. stack is ok.

Now when I put this ".env" file in secret docker the environment variables are not updated.

.... secrets: elk_secret: file: .env

services: elasticsearch: image: docker.elastic.co/elasticsearch/elasticsearch:7.16.3 secrets:

elk_secret .... Is there a trick to be able to put the ".env" file in docker secret and have the stack environment variables updated.
