Deploy a Netdata container for offline system

[kavishgr]

I'm trying the exact same thing as mentioned in this section but inside a container instead. I came up with the following Dockerfile:

FROM alpine:latest

# Set the working directory inside the container
WORKDIR /netdata-on-prem

# Copy the install.sh and netdata-x86.gz.run files into the container's working directory
COPY sha256sums.txt channel install.sh kickstart.sh netdata-x86_64-latest.gz.run /netdata-on-prem/

# Make install.sh executable (assuming it needs to be executed)
RUN chmod +x install.sh

# Run the install.sh script which will install and configure Netdata
RUN ./install.sh --no-updates  --disable-telemetry

# Expose the ports that Netdata uses (19999 by default for web UI and monitoring)
EXPOSE 19999

# Set the command to start Netdata when the container runs
CMD ["/opt/netdata/bin/netdata", "-D"]

Build the image:

docker build -t netdata-onprem .

Running the container(got the command in the docker install section from the documentation):

docker run -d --name=netdata \
  --pid=host \
  --network=host \
  -v netdataconfig:/etc/netdata \
  -v netdatalib:/var/lib/netdata \
  -v netdatacache:/var/cache/netdata \
  -v /etc/passwd:/host/etc/passwd:ro \
  -v /etc/group:/host/etc/group:ro \
  -v /proc:/host/proc:ro \
  -v /sys:/host/sys:ro \
  -v /etc/os-release:/host/etc/os-release:ro \
  -v /var/run/docker.sock:/var/run/docker.sock:ro \
  --restart unless-stopped \
  --cap-add SYS_PTRACE \
  --cap-add SYS_ADMIN \
  --security-opt apparmor=unconfined \
  netdata-onprem

Currently, I have the Netdata agent up and running, and there's an accessible dashboard at http://localhost:19999/. However, I'm unsure if I've built and run the image/container correctly. Unfortunately, I'm not receiving any metrics for Docker containers. Do I need a plugin/chart to enable this functionality?

The docs are very clear and state that all collectors are automatically installed with every Netdata installation. There's no need to manually install collectors to collect metrics from new sources. .

Here's a screenshot:

Hey, @kavishgr. You are correct, you haven't built the image correctly. You need to use ENTRYPOINT and not CMD. The entrypoint should be run.sh.

@kavishgr what is the reason you don't use our official docker image? What modification do you need to do?
