Clone repository:

git clone https://github.com/serxa/stress_memcg.git

Build the binary:

cd stress_memcg
./build.sh

Prebuilt binaries

You can find binaries for x86-64 and aarch64 in Releases

cd stress_memcg
mkdir -p build
wget https://github.com/serxa/stress_memcg/releases/download/v1.0.0/stress_memcg_x86-64 -O build/stress_memcg
... or ...
wget https://github.com/serxa/stress_memcg/releases/download/v1.0.0/stress_memcg_aarch64 -O build/stress_memcg
chmod +x build/stress_memcg

Running with Docker

Install docker to run binary inside cgroup

Setup you shell session with:

cd stress_memcg
source env.sh.inc

Then use run-test and stop-test to run and stop the stress test.

Running with containerd

Setup you shell session with:

cd stress_memcg
source env.sh.inc

Then use run-ctr-test and stop-ctr-test to run and stop the stress test.

Running on GKE node

First, you'll need to obtain the node shell.

Run and exit toolbox to create a folder without noexec mount flag. It should output a path for you, use it to construct the path to enter by adding /var/lib for example:

# toolbox
Spawning container root-us.gcr.iocos-cloudtoolbox-v12345678 on /var/lib/toolbox/root-us.gcr.io_cos-cloud_toolbox-v12345678.
Press Ctrl-] three times within 1s to kill container.
(Hit Ctrl-D)
cd /var/lib/toolbox/root-us.gcr.io_cos-cloud_toolbox-v12345678/var/lib

In the folder download the repo and the binary:

git clone https://github.com/serxa/stress_memcg.git
cd stress_memcg
mkdir -p build
wget https://github.com/serxa/stress_memcg/releases/download/v1.0.0/stress_memcg_x86-64 -O build/stress_memcg
chmod +x build/stress_memcg

Setup shell and run the test

source env.sh.inc
run-test

Optional. On another node shell run checker:

cd /var/lib/toolbox/root-us.gcr.io_cos-cloud_toolbox-v12345678/var/lib/stress_memcg
source env.sh.inc
checker `pgrep stress_memcg`
