Is it possible to launch the container for X minutes ?
i would like to activate the vpn container for 10 minutes and next the 10 minutes the container stop automatically.
This needs to be handled outside of docker.
You could create a simple bash script that:
- starts the container
- sleeps 10 minutes
- stops the container
it’s a solution thanks
but no param in docker ?
No. Docker has no option to stop a container after a certain time. You need to script that.
when i execute the start and stop, the container is a exited status
is it possible to down of ram the container ?.
When i start the server the container is not in the list of executing container because the status restart mode is off
Please explain. A stopped container does not occupy ram.
Makes sense, doesn’t it? If you want your container to be started with the server, then you could use a systemd unit or use whatever your os supports during startup to run commands.
You could use something like this:
/etc/systemd/system/docker.mycontainer.service, where mycontainer can be changed to whatever you like. It does not even have to match the description inside the unit block:
[Unit] Description=mycontainer After=docker.service Requires=docker.service [Service] Restart=no RuntimeMaxSec=600 ExecStart=/usr/bin/docker run --rm --name %n myimage [Install] WantedBy=multi-user.target
--rm remove the container if stopped.
--name %n will use the description as container name. You want it to be a single word
myimage needs to be replaced with the image you want to use.
Then start the systemd unit:
systemctl start docker.mycontainer. To make it start each time the server starts use
systemctl enable docker.mycontainer
Note: the service WILL be marked as failed after it reached the RuntimeMaxSec, and the container will be deleted then.
Note2: all of the above needs to be done as root.
Please bear in mind that this is only to give you an idea how a solution could look like. If it doesn’t work on the spot or doesn’t work as you want it, please research the topic. Starting processes on server start is not a problem in the docker domain, it is a problem of the os domain.
