# Notes on docker
|
||
|
|
|
||
|
|
Docker uses a lot of system resources without your knowledge.
|
||
|
|
This notes describe how to find out and what to do about it.
|
||
|
|
|
||
|
|
## Find out space used by docker:
|
||
|
|
```
|
||
|
|
sudo docker system df
|
||
|
|
```
|
||
|
|
and
|
||
|
|
```
|
||
|
|
sudo du -sh /var/lib/docker/
|
||
|
|
```
|
||
|
|
|
||
|
|
## What to do about it?
|
||
|
|
|
||
|
|
### 1. Remove unused layers (very effective)
|
||
|
|
```
|
||
|
|
sudo docker system prune
|
||
|
|
```
|
||
|
|
### 2. Remove unused images
|
||
|
|
```
|
||
|
|
sudo docker image prune -a
|
||
|
|
```
|
||
|
|
### 3. Clear out unused volume data
|
||
|
|
```
|
||
|
|
sudo docker volume prune
|
||
|
|
```
|
||
|
|
|
||
|
|
### 4. Clear out builder cache
|
||
|
|
```
|
||
|
|
sudo docker builder prune
|
||
|
|
```
|
||
|
|
|
||
|
|
### 5. Remove unused containers:
|
||
|
|
```
|
||
|
|
sudo docker container prune
|
||
|
|
```
|
||
|
|
