RHCS Dashboard Dev. Env.

Quick Install

1. Clone the Ceph repo (both --depth 1 --single-branch are optional flags but they'll dramatically reduce the amount of data transferred and stored):

   git clone --depth 1 --single-branch git@github.com:ceph/ceph.git

2. Clone this repo:

   git clone https://github.com/rhcs-dashboard/ceph-dev.git

3. Enter ceph-dev directory.
4. To install docker and docker-compose, if you're using:
   • Fedora: sudo bash ./docker/scripts/install-docker-compose-fedora.sh
   • CentOS/RHEL: sudo bash ./docker/scripts/install-docker-compose-centos-rhel.sh
   • Other OSes: please check this. Additionally, please ensure that SELinux is running in permissive mode:

     setenforce 0
     sed -i -E 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

5. Use .env.example template for ceph-dev configuration: cp .env.example .env, edit .env and modify CEPH_REPO_DIR=/path/to/... to point to the directory where you cloned the Ceph repo (step #1)
6. Download the container images: docker-compose pull
7. Launch it (for a minimal Ceph-only deployment):

   docker-compose up -d ceph
   

   or (for Ceph + monitoring stack):

   docker-compose up -d ceph grafana prometheus alertmanager node-exporter
   

8. Check how things are going with docker-compose logs -f ceph:
   • After a couple of minutes (aprox.) it'll finally print All done.
9. The dashboard will be available at: https://localhost:11000 with credentials: admin / admin.

Advanced Installation

• Clone Ceph:

git clone git@github.com:ceph/ceph.git

• Clone rhcs-dashboard/ceph-dev:

git clone git@github.com:rhcs-dashboard/ceph-dev.git

• In ceph-dev, create .env file from template and set your local values:

cd ceph-dev
cp .env.example .env

• Install Docker Compose by running the following, depending on your OS:

# Fedora:
sudo bash ./docker/scripts/install-docker-compose-fedora.sh

# CentOS 7 / RHEL 7:
sudo bash ./docker/scripts/install-docker-compose-centos-rhel.sh

If you ran the above script, then you can run docker and docker-compose without sudo if you log out and log in.

• Download docker images:

docker-compose pull

• Optionally, set up git pre-commit hook:

docker-compose run --rm -e HOST_PWD=$PWD ceph /docker/ci/pre-commit-setup.sh

Usage

You don't need to build ceph if you've set CEPH_IMAGE=rhcsdashboard/ceph-rpm:... container image (the default).

• Start ceph + dashboard feature services:

docker-compose up -d

# Only ceph:
docker-compose up -d ceph

• Display ceph container logs:

docker-compose logs -f ceph

• Access dashboard with credentials: admin / admin

https://localhost:$CEPH_HOST_PORT

Access dev. server dashboard when you see in container logs something like this:

ceph                 | *********
ceph                 | All done.
ceph                 | *********

http://localhost:$CEPH_PROXY_HOST_PORT

• Restart dashboard module:

docker-compose exec ceph /docker/restart-dashboard.sh

• Add OSD in 2nd host (once ceph dashboard is accessible):

docker-compose up -d --scale ceph-host2=1

• Stop all:

docker-compose down

• Build Ceph:

# Set a build-ready image and your local ccache path in .env file:
CEPH_IMAGE=rhcsdashboard/ceph:master  # DO NOT use ceph-rpm:... image.
HOST_CCACHE_DIR=/path/to/your/local/.ccache

docker-compose run --rm ceph /docker/build-ceph.sh

# Access here: http://localhost:11001

Grafana

If you have started grafana, you can access it at:

http://localhost:$GRAFANA_HOST_PORT/login

Prometheus

If you have started prometheus, you can access it at:

http://localhost:$PROMETHEUS_HOST_PORT

Single Sign-On (SSO)

Keycloak (open source Identity and Access Management solution) will be used for authentication, so localhost port 8080 must be available.

• Start Keycloak:

docker-compose up -d --scale keycloak=1 keycloak

You can access Keycloak administration console with credentials: admin / keycloak

http://localhost:8080 or https://localhost:8443

• Enable dashboard SSO in running ceph container:

docker-compose exec ceph /docker/sso/sso-enable.sh

• Access dashboard with SSO credentials: admin / ssoadmin

https://localhost:$CEPH_HOST_PORT

• Disable dashboard SSO:

docker-compose exec ceph /docker/sso/sso-disable.sh

RGW Multi-Site

• Set appropriate values in .env:

RGW_MULTISITE=1

• Start ceph (cluster 1) + ceph cluster 2:

docker-compose up -d --scale ceph-cluster2=1

• Run 100s duration benchmark:

docker-compose exec ceph-cluster2 bash
hsbench -a <rgw-user-access-key> -s <rgw-user-secret-key> -u http://127.0.0.1:8000 -z 4K -d 100 -t 10 -b 10

Access local dashboard connected to remote cluster

• Set appropriate values in .env:

REMOTE_DASHBOARD_URL=http://remote.ceph.cluster.com:8443

• Start only ceph:

docker-compose up -d ceph

Build and push an image to docker registry:

If you want to update an image, you'll have to edit image's Dockerfile and then:

• Build image:

docker build -t {imageName}:{imageTag} -f {/path/to/Dockerfile} ./docker/ceph

# Example:
docker build -t rhcsdashboard/ceph:master -f ./docker/ceph/master/Dockerfile  ./docker/ceph

• Optionally, create an additional tag:

docker tag {imageName}:{imageTag} {imageName}:{imageNewTag}

# Example:
docker tag rhcsdashboard/ceph:master rhcsdashboard/ceph:latest

• Log in to rhcs-dashboard docker registry:

docker login -u rhcsdashboard

• Push image:

docker push {imageName}:{imageTag}

# Example:
docker push rhcsdashboard/ceph:master

Start Ceph 2 (useful for parallel development)

• Set your CEPH2_ local values in .env.

• Start ceph2 + ceph + ...:

docker-compose up -d --scale ceph2=1

# Start ceph2 but not ceph:
docker-compose up -d --scale ceph2=1 --scale ceph=0
