When the CI/CD of the current version of web automation triggers execution, the use case time increases significantly compared with the previous version, and then there is no submission and maintenance of web automation use cases. Check the reasons and decide to upgrade the Chrome version in the server to see if it can effectively reduce the time.

	echo "ACCOUNT=${ACCOUNT}"
	echo "PASSWORD=${PASSWORD}"
  echo "MODULES=${MODULES}"
  echo "MOD_MODULES=${MOD_MODULES}"
  echo "URL=${URL}"
	echo "DOCKER_LOG_PATH=${DOCKER_LOG_PATH}"

	echo ""

    docker run -d -v /dev/shm:/dev/shm -v /var/log:/var/log --rm --name ${DOCKER_LOG_FILE} \

        "/opt/run_branch.sh -B ${TEST_BRANCH} -P '-M ${MOD_MODULES} -U ${URL} -R -A ${ACCOUNT} -P ${PASSWORD} -D $DOCKER_LOG_PATH'"

From this shell, we know that when executed on the server, a new container will be created for different modules, so we need to modify the Chrome version in the image and upgrade the corresponding Chrome driver.

Based on imageid:877e53b69c39, there are two corresponding container instances, so we can enter a container, modify the file in the container, export it as a tar file, and then import the file as image.
implement

docker exec -it 87cf238c109b /bin/bash

When entering the container, we need to know the path of Chrome and check the Dockerfile

FROM ubuntu:16.04

RUN mkdir -p /home

There is a home folder in the root directory to download various installation packages

root@87cf238c109b:/# cd home
root@87cf238c109b:/home# ls
# result
google-chrome-stable_current_amd64.deb

Go to the usr/local/bin directory to check the current Chrome version

google-chrome -version

The version number before upgrading is 55

Since Chrome dependency has been installed before, we only need to download the latest installation package

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

Then unzip the installation package, which will automatically overwrite the current chrome version, and the plug-in will not change

sudo dpkg -i ./google-chrome-stable_current_amd64.deb

At this time, the version number is

Google Chrome 88.0.4324.182 

Then go to the website to find the chrome driver that matches the current version

wegt http://npm.taobao.org/mirrors/chromedriver/88.0.4324.96/chromedriver_linux64.zip

Unzip the downloaded file and put it in the following location

unzip chromedriver_linux64.zip
/usr/bin/chromedriver

After the file of the container is modified, we can exit the container for export

[root@localhost ~]# docker export -o optimistic_wing.tar optimistic_wing

Where - o means output to file, optimal_ wing. Tar is the target file, which is optimal_ Wing is the name of the source container;
After the export, use this tar file to import as a new image

[root@localhost ~]# docker import optimistic_wing.tar docker/robot-web-evn

After successful execution of docker image, you can see that a new image has been created.
