This command is used to log in to a Docker registry. Here is a breakdown of what each part of the command does:
-
echo "${password}"
: This echoes the value of thepassword
variable enclosed in double quotes. It is piped (|
) as input to thedocker login
command. -
docker login
: This is the Docker command to log in to a Docker registry. -
--username ${username}
: This flag specifies the username to be used for authentication.${username}
is a variable that holds the desired username. -
--password-stdin
: This flag tells Docker to read the password from stdin (standard input). The password is passed through theecho
command mentioned earlier.
Overall, this command takes the value of the password
variable, echoes it, and then inputs it as the password for the specified Docker registry along with the provided username.
