Mender Update installation

General Discussions
1

I am installing mender on my machine for OTA updates and app deployments.

Installing mender using

curl -fLsS https://get.mender.io -o get-mender.sh
# Added mender update component to instal list
sudo bash get-mender.sh

This did not work giving some version mismatch error

Then I installed mender-clinet4 which had the mender-update component,

mender-update --version
5.0.3

but it did not have the docker compose module as mentioned here. Tutorial: Docker Compose update | Mender documentation

I installed all these components on my machine and I got some error regarding missing files in modules.

I tried creating the artifact as both app and docker-compose.

mender-artifact write module-image   -T app   -n ${ARTIFACT_NAME}   -t ${DEVICE_TYPE}   -o ${OUTPUT_PATH}   -f docker-compose.yml
mender-artifact write module-image   -T docker-compose   -n ${ARTIFACT_NAME}   -t ${DEVICE_TYPE}   -o ${OUTPUT_PATH}   -f docker-compose.yml

Is there a documentation on how to get the whole pipeline working?

Im trying to use the docker artifact gen I m not sure if this is the latest method of doing this. As per the tutorial it uses a differnet component.

I am trting to run docker containers in my remote machine and i unable to create artifacts

What am i missing from the documentation to get it working?
For instance single file generation works fine.

You don’t need the Mender Client on the workstation.
My mender-artifact version is 4.2.0.

So the obvious things are

  1. update mender-artifact as described in Download | Mender documentation
  2. inspect your manifest file for errors, maybe start with the provided one for reference and then modify

Greetz,
Josef

Hi Josef,

thanks for checking this out.

I have upgraded the mender-artifact to 4.2.0

I still have the same error with both docker compose and docker gen. I am following the tutorial link as it is.

However I was able to create the artifact using mender-artifact command and when creating a release a container was started in my device

mender-artifact write module-image   -t jetson   -n  triton-23 -T docker -o triton-23.mender -m triton-metadata.json

cat triton-metadata.json
{
  "containers": ["nvcr.io/nvidia/tritonserver:23.10-py3"],
  "run_args": "--name tritonserver-new --runtime=nvidia --gpus all -p 9000:8000 -p 9001:8001 -p 9002:8002 --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -e MODEL_REPOSITORY=s3://my-bucket/models -e TRITON_AWS_MOUNT_DIRECTORY=/models --network host"
}

I m not sure how to make this part work with docker-compose though.

Hi @vini,

Okay, I think we’re getting closer here. There are two different Update Model available, which serve two different purposes.

Looking at your triton-metadata.json example, it sounds like you effectively want to deploy the nvcr.io/nvidia/tritonserver:23.10-py3 container, with --name tritonserver-new --runtime=nvidia --gpus all -p 9000:8000 -p 9001:8001 -p 9002:8002 --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -e MODEL_REPOSITORY=s3://my-bucket/models -e TRITON_AWS_MOUNT_DIRECTORY=/models --network host as run_args. I don’t have a matching board available to actually test the artifact, but creating it with

ARTIFACT_NAME="my-container-update-1.0"
DEVICE_TYPE="my-device-type"
OUTPUT_PATH=my-container-update-1.0.mender
DOCKER_IMAGES="nvcr.io/nvidia/tritonserver:23.10-py3"
/docker-artifact-gen \
  -n ${ARTIFACT_NAME} \
  -t ${DEVICE_TYPE} \
  -o ${OUTPUT_PATH} \
  --run-args '--name tritonserver-new --runtime=nvidia --gpus all -p 9000:8000 -p 9001:8001 -p 9002:8002 --shm-size=1g --ulimit memlock=-1 --ulimit stack=67108864 -e MODEL_REPOSITORY=s3://my-bucket/models -e TRITON_AWS_MOUNT_DIRECTORY=/models --network host'\
  ${DOCKER_IMAGES}

did work right away:

So my understanding is the the first thing is to choose the right approach for your requirements. :slight_smile:

hi @TheYoctoJester

The docker-artifact-gen works now. But I want to use docker compose to deploy my applications, I was testing to docker to see if something would work.

My jetson is prepared

I have installed the modules as per the documentation. I see that the docker-compose module is created under /usr/share/mender/app-modules/v1

While other tools are available under

/usr/share/mender/modules/v3# ls 
app  directory  docker  k8s  reboot  rootfs-image  rootfs-image-jetson  script  single-file

And I assume this is the reason why I cannot even get the docker compose work with the mender-artifact write-module command.

However I still have the same issue when trying to create a docker compose artifact. In the github repo i dont see docker compose in the master branch.

I have also tried doing the same steps as root and it had the same error as well.

Ok, so we are essentially down to this problem.

Is the machine which you are running this on special in some way? Which Linux distribution / version are you using?

Greetz,
Josef

Hey @TheYoctoJester

The machine is nothing special

vini@vini-ThinkPad-T490s:~/artifacts$ cat /etc/os-release 
PRETTY_NAME="Ubuntu 22.04.5 LTS"

The target machine is not relevant here i assume.
