docker-compose scale with sticky sessions

由 断了今生、忘了曾经 提交于 2019-12-09 13:38:01
问题 I have a webserver that requires websocket connection in production. I deploy it using docker-compose with nginx as proxy. So my compose file look like this: version: '2' services: app: restart: always nginx: restart: always ports: - "80:80" Now if I scale "app" service to multiple instances, docker-compose will perform round robin on each call to the internal dns "app". Is there a way to tell docker-compose load balancer to apply sticky sessions? Another solution - is there a way to solve it

How to connect Docker web app container to Docker PostgreSQL container?

由 假装没事ソ 提交于 2019-12-09 13:23:14
问题 I'm practicing making a Golang web app that interacts with a PostgreSQL database, each running on their own container. I'm running the containers with docker-compose up But I seem to be failing on getting the postgres container properly set up. For brevity, links to Dockerfile s and other settings files are on this gist (let me know if you want it here instead). version: '2' services: web_app: build: dockerfiles/web_app ports: - "9000:9000" volumes: - .:/go/src/gitlab.com/repo/web_app # links

Docker error: invalid reference format: repository name must be lowercase

由 我的梦境 提交于 2019-12-09 05:02:35
问题 Ran into this Docker error with one of my projects: invalid reference format: repository name must be lowercase What are the various causes for this generic message? I already figured it out after some effort, so I'm going to answer my own question in order to document it here as the solution doesn't come up right away when doing a web search and also because this error message doesn't describe the direct problem Docker encounters. 回答1: A "reference" in docker is a pointer to an image.
