无法使用docker 命令搜g++?

Question

docker search g++
FATA[0000] Error response from daemon: Invalid repository name (g++), only [a-z0-9-_.] are allowed
咋回事?
名字里就是有加号,为啥不能搜:(

Answer 1

The error is very clear[a-z0-9-_.]
A valid container name only contains the following characters

1. lower case letters a-z
2. Underline
3. polka dots
4. Horizontal line
