## How to update CVAT
|
|
|
|
Before updating, please follow the [backup guide](/docs/administration/advanced/backup_guide/)
|
|
and backup all CVAT volumes.
|
|
|
|
To update CVAT, you should clone or download the new version of CVAT and rebuild the CVAT docker images as usual.
|
|
|
|
```sh
|
|
docker-compose build
|
|
```
|
|
|
|
and run containers:
|
|
|
|
```sh
|
|
docker-compose up -d
|
|
```
|
|
|
|
Sometimes the update process takes a lot of time due to changes in the database schema and data.
|
|
You can check the current status with `docker logs cvat`.
|
|
Please do not terminate the migration and wait till the process is complete.
|
|
|
|
## Kibana app works, but no logs are displayed
|
|
|
|
Make sure there aren't error messages from Elasticsearch:
|
|
|
|
```sh
|
|
docker logs cvat_elasticsearch
|
|
```
|
|
|
|
If you see errors like this:
|
|
|
|
```sh
|
|
lood stage disk watermark [95%] exceeded on [uMg9WI30QIOJxxJNDiIPgQ][uMg9WI3][/usr/share/elasticsearch/data/nodes/0] free: 116.5gb[4%], all indices on this node will be marked read-only
|
|
```
|
|
|
|
You should free up disk space or change the threshold, to do so check: [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/disk-allocator.html).

|
## How to change default CVAT hostname or port
|
|
|
|
The best way to do that is to create docker-compose.override.yml and override the host and port settings here.
|
|
|
|
version: "3.3"
|
|
|
|
```yaml
|
|
services:
|
|
cvat_proxy:
|
|
environment:
|
|
CVAT_HOST: example.com
|
|
ports:
|
|
- '80:80'
|
|
```
|
|
|
|
Please don't forget to include this file in docker-compose commands
|
|
using the `-f` option (in some cases it can be omitted).
|
|
|
|
## How to configure connected share folder on Windows
|
|
|
|
Follow the Docker manual and configure the directory that you want to use as a shared directory:
|
|
|
|
- [Docker toolbox manual](https://docs.docker.com/toolbox/toolbox_install_windows/#optional-add-shared-directories)
|
|
- [Docker for windows (see FILE SHARING section)](https://docs.docker.com/docker-for-windows/#resources)
|
|
|
|
After that, it should be possible to use this directory as a CVAT share:
|
|
|
|
```yaml
|
|
version: '3.3'
|
|
|
|
services:
|
|
cvat:
|
|
volumes:
|
|
- cvat_share:/home/django/share:ro
|
|
|
|
volumes:
|
|
cvat_share:
|
|
driver_opts:
|
|
type: none
|
|
device: /d/my_cvat_share
|
|
o: bind
|
|
```
|
|
|
|
## How to make unassigned tasks not visible to all users
|
|
|
|
Set [reduce_task_visibility](https://github.com/openvinotoolkit/cvat/blob/develop/cvat/settings/base.py#L424)
|
|
variable to `True`.
|
|
|
|
## Where are uploaded images/videos stored
|
|
|
|
The uploaded data is stored in the `cvat_data` docker volume:
|
|
|
|
```yml
|
|
volumes:
|
|
- cvat_data:/home/django/data
|
|
```
|
|
|
|
## Where are annotations stored
|
|
|
|
Annotations are stored in the PostgreSQL database. The database files are stored in the `cvat_db` docker volume:
|
|
|
|
```yml
|
|
volumes:
|
|
- cvat_db:/var/lib/postgresql/data
|
|
```
|
|
|
|
## How to mark job/task as completed
|
|
|
|
The status is set by the user in the [Info window](/docs/manual/basics/top-panel/#info)
|
|
of the job annotation view.
|
|
There are three types of status: annotation, validation or completed.
|
|
The status of the job changes the progress bar of the task.
