Docker Create tomcat Error standard_init_linux.go:211: exec user process caused “no such file or directory”

Using the command before Tomcat creates a container

docker pull tomcat
docker run -it -P tomcat

Report the following error: Standard_ init_ linux.go:211 : exec user process caused “no such file or directory”

Solution:

Use other Tomcat images to create Tomcat container and run it successfully

docker run -d --name tomcat -p 8888:8080 registry.cn-hangzhou.aliyuncs.com/youdao/tomcat

Speculation: before using the docker hub with the highest number of stars, there was a problem, indicating that this kind of file and directory could not be found. Maybe the image was damaged when downloading

If we use the new container to download and run, it’s OK

Personal test!!! This error is the download image is damaged! The docker needs to be unloaded clearly. Remember to clear all the associated file directories
