Docker – Show the running processes in docker container

We will help you to understand how to show the running processes in docker container. For this, we use “docker top container_name” command.

“docker top” command can be used with various options to show the running processes of a docker container.

Usage:

docker top container_name_1

How docker top command works ?

• When we use docker top command with container name, It shows running processes having process ID, parent process ID, create time and total time of processes running.
• One container can have multiple processes. So with this command, we can also get details of specific process.
• If you give invalid process ID in top command, It won’t show any thing.

Example:

% docker top redis

UID   PID   PPID   C   STIME   TTY   TIME     CMD
999   2552  2527   0   10:33    ?    00:00:03 redis-server *:6379


% docker top redis 2552  >> Here, 2552 is a process ID

PID     TTY     STAT     TIME     COMMAND
2552     ?      Ssl+     0:04     redis-server *:6379


% docker top redis 2520  >> Here, 2520 is a invalid process ID.

PID TTY STAT TIME COMMAND
