Move Fleio Docker installation

Use this guide to copy or move a Fleio Docker installation (including database, settings and customizations) to another server.

This guide only applies for Docker to Docker Fleio deployment method. If you are migrating from a legacy DEB/RPM Fleio install follow Migrate DEB/RPM to Fleio Docker deployment.

The guide applies when copying an installation, that is you keep the old installation running and also run Fleio on the new installation, and when moving the old installation, in other words you are stopping the old server and after copying data, you will only run Fleio on the new server. There are notes in the guide regarding copying and moving.

Here are some typical use cases for this guide:

  • You have a lab evaluation of Fleio and you want to keep all the settings and move to a production server.

  • You have a production server, and you want to duplicate the database and all the settings to a staging installation, where you can test Fleio upgrades or customizations, before applying them to production.

  • You want to move your production Fleio server to another production server.

1. Install Fleio from scratch on the new server

Note

Make sure you install the exact same version on the new server as the version on the old server.

You need an extra license key to install Fleio on the new server. For staging/development installations, contact support to obtain a free license key for each Fleio license you have purchased.

Decide on the URL to use for your new Fleio installation and use it for the FLEIO_FRONTEND_URL variable below. Note that the URL is linked to the license during installation.

After the initial Fleio installation, if you later change the installation URL or the secret key, you will need a Fleio license reset. Contact Fleio support to reset your license.

For moving a (production) installation, this guide assumes that you have a strategy for pointing your users to the new Fleio installation. As last production move step, you can move IP address to new server, update DNS settings etc. This guide does not cover this part.

http://192.168.99.2 and https://mydomain.com are used below as examples. Replace with your URLs.

1.1. Installing Fleio version 2022.11 or newer

Install the exact same Fleio version as the one on the old server.

If you are moving Fleio version 2022.11 or newer, you can also specify in the install command the FLEIO_DJANGO_SECRET_KEY from the old server. This will spare you to ask support for a license reset.

To get the FLEIO_DJANGO_SECRET_KEY run this on the old server (from which you are migrating):

fleio bash cat fleio/fleiosettings/settings.py|grep -m 1 SECRET_KEY
# you'll get something like:
# SECRET_KEY = '<< the secret key >>'
# Copy << the secret key >>

Run the install command on the new server (to which you are migrating).

curl -s -o install https://fleio.com/install && sudo \
FLEIO_LICENSE_ID="<< license id >>" \
FLEIO_LICENSE_KEY="<< license key >>" \
FLEIO_FRONTEND_URL="http://192.168.99.2" \
FLEIO_DJANGO_SECRET_KEY="<< the secret key >>" \
bash install << replace with Fleio version to install >>

The install script will ask you for details like time zone. You may fill any values, they are overwritten anyway when you later copy the settings from the old Fleio installation.

1.2. Installing Fleio version older than 2022.11

Install the exact same Fleio version as the one on the old server.

Run the install command on the new server (to which you are migrating). Since a secret key is randomly generated during installation, and you will later need to set this value to the one from the old server, a license reset will be required. After completing the migration steps, contact support to reset your license.

curl -s -o install https://fleio.com/install && sudo \
FLEIO_LICENSE_ID="<< license id >>" \
FLEIO_LICENSE_KEY="<< license key >>" \
FLEIO_FRONTEND_URL="http://192.168.99.2" \
bash install << replace with Fleio version to install >>

The install script will ask you for details like time zone. You may fill any values, they are overwritten anyway when you later copy the settings from the old Fleio installation.

2. Copy settings from the old server

Note

The following commands work for Fleio version 2022.11 and newer. If you have an older version, replace the - (minus) in the container names with _ (underscore). E.g., fleio-backend-1 is fleio_backend_1 in Fleio versions older than 2022.11.

On the old server, copy the settings files from Docker containers to current host path:

docker cp fleio-frontend-1:/var/webapps/fleio/frontend/enduser/assets/config/enduser.config.json enduser.config.json
docker cp fleio-frontend-1:/var/webapps/fleio/frontend/staff/assets/config/staff.config.json staff.config.json
docker cp fleio-backend-1:/var/webapps/fleio/project/fleio/fleiosettings/settings.py settings.py

Use scp command a or a similar tool to copy the three files above (settings.py, enduser.config.json and staff.config.json) from the old server to the new server.

While logged in to the new server, copy the settings files from host to Docker containers (make sure the three files are in the current path):

docker cp enduser.config.json fleio-frontend-1:/var/webapps/fleio/frontend/enduser/assets/config/enduser.config.json
docker cp staff.config.json fleio-frontend-1:/var/webapps/fleio/frontend/staff/assets/config/staff.config.json
docker cp settings.py fleio-backend-1:/var/webapps/fleio/project/fleio/fleiosettings/settings.py

Run fleio edit enduser.config.json and update the backendApiUrl to the URL you are using on the new server. For example, for value "backendApiUrl": "//mydomain.com/backend/api/",, only replace mydomain.com. Do not add http or https.

Run fleio edit staff.config.json and update the "backendApiUrl": "//mydomain.com/backend/staffapi/" just like above.

While still logged in to the new server, copy the database password shown by command:

cat /home/fleio/compose/secrets/.db_password

Then run fleio edit settings.py and update the 'PASSWORD': '<< copy here>>', value from the DATABASES = { section.

If you are changing the old URL to a new URL, while still editing settings.py, update the following values based on the URL you are using on the new server:

  • ALLOWED_HOSTS = ['mydomain.com'] - do not add http/s or a trailing slash

  • FRONTEND_URL = 'https://mydomain.com'

3. Copy the database

Disable periodic tasks on the old server. You can find this setting in the staff panel, Settings > General > Advanced settings tab. After checking Disable periodic tasks, wait a couple of minutes for this to take effect. Keep in mind that you will later need to re-enable periodic tasks, there’s a note about this in a step below.

You can confirm that periodic tasks are no longer running by using this command:

fleio list periodic

Warning

If you are moving a Fleio installation (production or not), you need to stop Fleio on the old server. This way you ensure that there are no changes performed on the old database and you will have the latest version on the new server.

When moving a production installation, it is highly recommended that you first perform a test move, and keep the old installation running. Once you confirm that the test move is successful, perform the steps again (starting with this one) on the final move (with old installation stopped).

Optionally, stop Fleio on the old server if you are performing a move, not a copy:

cd /home/fleio/compose/
# on Fleio version 2022.11 or newer, run:
docker compose down
docker compose up -d db
# on Fleio version 2022.10 or older, run:
# docker-compose down
# docker-compose up -d db

Backup the database from the old server:

fleio mysqldump | gzip > fleio_backup.gz

Copy the fleio_backup.gz backup file, by using scp, from the old server to the new server in /home/fleio/compose path.

Restore from backup on the new server (uncomment the corresponding lines based on your Fleio version:

cd /home/fleio/compose
db_pass=$(cat secrets/.db_password)
# on Fleio version 2022.11 or newer, run:
# docker compose down
# docker compose up -d db
# on Fleio version 2022.10 or older, run:
# docker-compose down
# docker-compose up -d db
# on Fleio version 2022.10 or older, run:
# gunzip -c fleio_backup.gz | docker-compose exec -T db mysql fleio -u fleio -p"$db_pass"
# on Fleio version 2022.11 or newer, run:
# gunzip -c fleio_backup.gz | docker compose exec -T db mysql fleio -u fleio -p"$db_pass"

4. Set a new OpenStack notifications pool (when copying)

Warning

After copying the database, your new installation contains the same OpenStack notifications pool name.

This means if the old and the new installations are running, some of the OpenStack notifications would be consumed by the old installation and some by the new. This has serious consequences: OpenStack objects status may not get updated and usage/cost tracking will not work correctly.

If you are moving Fleio (not copying) and the old installation will remain stopped, this step is not necessary.

cd /home/fleio/compose/
db_pass=$(cat secrets/.db_password)
sql="UPDATE conf_option SET value='new-pool' WHERE section='OPENSTACK_PLUGIN' AND field='notifications_pool';"
# on Fleio version 2022.10 or older, run:
# echo "$sql" | docker-compose exec -T db mysql fleio -u fleio -p"$db_pass"
# on Fleio version 2022.11 or newer, run:
# echo "$sql" | docker compose exec -T db mysql fleio -u fleio -p"$db_pass"

5. Copy Fleio customizations (optional)

If you have made any customizations to your (old) Fleio installation you need to copy the corresponding files from /home/fleio/compose to the same path on the new server:

  • docker-compose.override.yml

  • files and directories you have created to customize the Docker images

  • .env, if you customized stuff like number of uWSGI processes. Note that you need to merge the values for domain and URL if they are different on the new server.

Note

Do not copy the full /home/fleio/compose directory, as this will overwrite settings you do not want, like database password (/home/fleio/compose/secrets/.db_password) or Fleio installation URL (in .env)

6. Recreate Fleio containers

On the new server, run:

fleio recreate

7. Ask for license reset

If you have changed the new installation secret key or URL after the initial installation, your new installation will not work anymore without a license reset. Contact the Fleio support to reset your license.

8. Enable periodic tasks

If the new installation is a production installation, you need to enable periodic tasks. If it’s a staging/development installation, which just shadows the main/production installation, do not enable periodic tasks.

Enabling periodic tasks will start clients processing: calculate up-to-date usage, send email notification, automatically suspend and terminate services, based on settings.

Enable periodic tasks on the new server. Uncheck Disable periodic tasks from the staff panel, Settings > General > Advanced settings tab.

If you want to keep the old Fleio installation running while the new installation is also running, make sure you changed the pool name on the new server (step 4 above) and uncheck Disable periodic tasks on the old sever.

9. Sync OpenStack

To synchronize OpenStack objects run:

fleio sync
