tutorial-environment's Introduction

Sample application for tutorials

This repository contains the environment for completing the tutorials at grafana.com/tutorials.

Prequisites

You will need to have the following installed locally to complete this workshop:

NOTE: If you're running Docker for Desktop for macOS or Windows, Docker Compose is already included in your installation.

Login

To log in browse to localhost:3000.

NOTE: To facilitate the demo, login has been disabled, and anonymous access is granted admin privileges. For security reasons, we advise keeping login enabled in your Grafana instance.

If you want to follow the tutorial with login enabled, you can comment the following lines of the docker-compose file

  - GF_AUTH_ANONYMOUS_ORG_ROLE=Admin 
  - GF_AUTH_ANONYMOUS_ENABLED=true
  - GF_AUTH_BASIC_ENABLED=false

Once login is enabled, the default username and password is admin:admin

Running

To start the sample application and the supporting services:

docker-compose up -d

Permission denied

I am running your app using Openshift as:

oc new-app https://github.com/grafana/tutorial-environment.git --context-dir=app

The app builds correct but then:

hesteban-redhat.com@bastion ~]$ oc get pods
NAME                                    READY   STATUS             RESTARTS   AGE

[hesteban-redhat.com@bastion ~]$ oc logs tutorial-environment-54ff5f7f48-jzwj8
/bin/sh: can't create /var/log/tns-app.log: Permission denied

Do you know what can I do to avoid the Permission denied?

Unable to docker-compose up on WSL2

System: WSL2, Ubuntu 20.04.3 LTS
Docker Version: Docker version 20.10.10, build b485636

When I pulled and ran docker-compose up -d I received the message
Error response from daemon: path /<path>/tutorial-environment/prometheus is mounted on / but it is not a shared mount.

I updated the docker-compose yml from
- ./prometheus/:/etc/prometheus/
to
- ./prometheus:/etc/prometheus

This fixed my issue. Not sure what impact this will have on other systems or docker versions

error: open /tmp/build/inputs/Dockerfile: no such file or directory in Openshift

Going to the app folder in your repo and doing:

$ oc new-app $(pwd) --strategy=docker

Gives:

Do you know the possible reason?

Get error ‘Connection reset by peer ’ when access by host？

I set up the application follow the tutorial https://grafana.com/tutorials/grafana-fundamentals/#2
All services are up-and-running:

But when I try to access the sample application in host, I get error 'Connection reset by peer',

Cannot finish setup

Second time to run this demo on my mac and got the following error when I tried to execute the docker-compose:

Raspberry Pi: App build error

Hi there!

When docker-compose up runs, the app and db seem to exit.

When attempting to docker-compose up the app alone, it gives the error: /app: line 1: syntax error: unexpected "("

Thanks :)

App fails to start

When I run docker-compose up -d; most of the containers start except "tutorial-environment_app" and "grafana/tns-db:latest". In looking at the docker logs, the following errors are reported:

In the "app" the error is:

./app: 1: Syntax error: "(" unexpected

In the db container, the error is:

standard_init_linux.go:228: exec user process caused: exec format error

I am running this on a Raspberry PI with the 64 bit OS .

Any ideas?

Clone is getting aborted

If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

loki can not start

I just clone the tutorial and start it.but loki can not start.

➜ tutorial-environment git:(master) docker-compose ps
Name Command State Ports

tutorial-environment_app_1 /bin/sh -c /app http://db ... Up 0.0.0.0:8081->80/tcp
tutorial-environment_db_1 /db Up 0.0.0.0:8082->80/tcp
tutorial-environment_grafana_1 /run.sh Up 0.0.0.0:3000->3000/tcp
tutorial-environment_loki_1 /usr/bin/loki -config.file ... Exit 1
tutorial-environment_prometheus_1 /bin/prometheus --config.f ... Up 0.0.0.0:9090->9090/tcp
tutorial-environment_promtail_1 /usr/bin/promtail -config. ... Up

so I pull latest grafana/loki again and restart,still the same.

docker-compose logs give me this hint:
loki_1 | failed parsing config: /etc/loki/local-config.yaml: not a valid duration string: "0"

can someone check the config yaml?

Podman on Fedora 36: /prometheus.yml: permission denied

Hello,

Trying to run the tutorial under Fedora 36 with podman. Downloading and setup succeed, but one of the containers exits right after launch. It says permission denied in the log:

$ podman logs tutorial-environment_prometheus_1 
ts=2022-10-16T15:47:44.754Z caller=main.go:438 level=error msg="Error loading config (--config.file=/etc/prometheus/prometheus.yml)" file=/etc/prometheus/prometheus.yml err="open /etc/prometheus/prometheus.yml: permission denied"

What can I do to make Prometheus start normally, and finally complete the tutorial?

Thanks,
FWieP
