[英]Variable substitution in docker-compose.yml file when running docker-compose with sudo
[英]Accessing environmental variable inside of docker-compose.yml file when using docker-compose up
! 嘗試使以下內容工作docker-compose.yml
:
version: "3.3"
services:
node:
image: node:$CUSTOM_NODE_VERSION
environment:
- NODE_ENV=test
entrypoint: ["npm", "run", "lint"]
嘗試開始時:
$ docker-compose -f docker-compose.yml up --remove-orphans --force-recreate --abort-on-container-exit
The CUSTOM_NODE_VERSION variable is not set. Defaulting to a blank string.
no such image: node:: invalid reference format
我從.gitlab-ci.yml
:
Node:
stage: Node
script:
- echo $CUSTOM_NODE_VERSION
- docker-compose -f docker-compose.lint.yml up --remove-orphans --force-recreate --abort-on-container-exit
沒什么好看的。 有誰知道我如何訪問docker docker-compose.yml
文件中的$ CUSTOM_NODE_VERSION變量? 可能嗎
您可能沒有導出變量。 這樣做雖然應該可以:
CUSTOM_NODE_VERSION=10 docker-compose -f docker-compose.lint.yml up --remove-orphans --force-recreate --abort-on-container-exit
https://docs.docker.com/compose/environment-variables/
version: "3.3"
services:
node:
image: "node:${CUSTOM_NODE_VERSION}"
environment:
- NODE_ENV=test
entrypoint: ["npm", "run", "lint"]
我還必須在.gitlab-ci.yml
文件中導出變量(感謝Jack Gore):
Node:
stage: Node
script:
- export CUSTOM_NODE_VERSION=$CUSTOM_NODE_VERSION
- docker-compose -f docker-compose.lint.yml up --remove-orphans --force-recreate --abort-on-container-exit
