docker compose筆記

in computer-science

Container之間有關係時可以用docker command中的–link搞定
當有多個Container需要連結時我們會希望能撰寫一份設定檔定義Container之間的關係然後執行就好
這就是docker-compose在做的事
撰寫docker-compose.yml定義各Container link relation
然後run docker-compose up -d

Command

1
docker-compose -f ./docker-compose.yml up -d

docker-compose.yml example

以下設定表示
faceblock是ap server
zombodb_postgres是postgres database
zombodb_elastic是elasticsearch database
faceblock相依於zombodb_postgres
zombodb_postgres相依於zombodb_elastic
