## How to update CVAT
|
|
|
|
Before upgrading, please follow the official docker
|
|
[manual](https://docs.docker.com/storage/volumes/#backup-restore-or-migrate-data-volumes) 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](../../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](user_guide.md#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.
|
|
|
|
## How to install CVAT on Windows 10 Home
|
|
|
|
Follow this [guide](installation.md#windows-10).
|
|
|
|
## I do not have the Analytics tab on the header section. How can I add analytics
|
|
|
|
You should build CVAT images with ['Analytics' component](../../../components/analytics).
|
|
|
|
## How to upload annotations to an entire task from UI when there are multiple jobs in the task
|
|
|
|
You can upload annotation for a multi-job task from the Dasboard view or the Task view.
|
|
Uploading of annotation from the Annotation view only affects the current job.
|
|
|
|
## How to specify multiple hostnames for CVAT_HOST
|
|
|
|
```yaml
|
|
services:
|
|
cvat_proxy:
|
|
environment:
|
|
CVAT_HOST: example1.com example2.com
|
|
```
|
|
|
|
## How to create a task with multiple jobs
|
|
|
|
Set the segment size when you create a new task, this option is available in the
|
|
[Advanced configuration](user_guide.md#advanced-configuration) section.
