Docker Selenium Grid Setup:增加 node number and session number
https://dev.to/automationbro/docker-selenium-grid-setup-1lg4

Increasing the MAX_INSTANCES & MAX_SESSIONS for the Grid

So far we just have 1 instance of Chrome & Firefox, however, if you need to run multiple tests together, you'll need more instances spun up. You can do that quite easily by adding the parameters when running the docker container for Chrome and Firefox.

docker run -d --net grid -e HUB_HOST=selenium-hub -e NODE_MAX_INSTANCES=3 -e NODE_MAX_SESSION=3 -v /dev/shm:/dev/shm selenium/node-chrome-debug:3.141.59–20210422

You can pass NODE_MAX_INSTANCES and NODE_MAX_SESSION environment variables to add multiple instances of the browsers.

• NODE_MAX_INSTANCES: number of instances of the same version of the browser
• NODE_MAX_SESSION: number of browsers (any versions) that can run in parallel

Once you do that, you will see something like this below?:

如何安裝制定版本額docker-compose
1.查找到響應(yīng)版本

2.安裝的cmd

清除(關(guān)閉全部容器) ：docker kill (docker ps -a -q)
再次查看容器情況狠轻，運(yùn)行：docker ps –a 發(fā)現(xiàn)整個世界都清凈了礁蔗。

如何使用docker-compose mount:
https://code.visualstudio.com/remote/advancedcontainers/add-local-file-mount

• Docker Compose: Update (or extend) your docker-compose.yml with the following for the appropriate service:

  version: '3'
  services:
    your-service-name-here:
      volumes:
        - /local/source/path/goes/here:/target/path/in/container/goes/here:cached
        - ~:/host-home-folder:cached
        - ./data-subfolder:/data:cached
       # ...
  

If you've already built the container and connected to it, run Remote-Containers: Rebuild Container from the Command Palette (F1) to pick up the change. Otherwise run Remote-Containers: Open Folder in Container... to connect to the container.
