## 👨🏻💻 Problem Summary
|
||
|
||
#### 1. Unable to delete a specific image tag through the UI.
|
||
**Known Issue：** Deletion is not supported when using `registry` as a proxy cache.
|
||
|
||
**Related Issues：** [#3853](https://github.com/distribution/distribution/issues/3853)
|
||
|
||
#### 2. The pull speed from within China is not ideal.
|
||
**Known Issue：** The network route from your foreign server to China is suboptimal.
|
||
|
||
**Solutions：**
|
||
- (1) Enable BBR on the server to optimize network performance (with limited effect).
|
||
- (2) Switch to a server that has better network optimization for routes to China.
|
||
|
||
#### 3. How long does the registry image cache last, and how to adjust it?
|
||
**Known Issue：** The default cache time is 168 hours, which is 7 days. Adjust the cache time by modifying the ttl in the proxy configuration section of the configuration file
|
||
|
||
#### 4. Regarding the solution for pulling images from the 'Hub' public namespace with or without adding the 'library' prefix when using a mirror registry for acceleration.
|
||
|
||
- This scheme was provided by a senior member in the communication group and has been implemented and tested through Nginx.
|
||
```shell
|
||
http {
|
||
map $http_upgrade $connection_upgrade {
|
||
default upgrade;
|
||
'' close;
|
||
}
|
||
|
||
server {
|
||
listen 80;
|
||
server_name hub.your_domain.com;
|
||
|
||
# 在docker hub的配置中添加下面的location规则
|
||
location ~ ^/v2/([^/]+)/(manifests|blobs)/(.*)$ {
|
||
rewrite ^/v2/(.*)$ /v2/library/$1 break;
|
||
proxy_pass http://127.0.0.1:51000;
|
||
proxy_set_header Host $host;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header REMOTE-HOST $remote_addr;
|
||
proxy_set_header Upgrade $http_upgrade;
|
||
proxy_set_header Connection $connection_upgrade;
|
||
proxy_http_version 1.1;
|
||
add_header X-Cache $upstream_cache_status;
|
||
}
|
||
|
||
location / {
|
||
proxy_pass http://127.0.0.1:51000;
|
||
proxy_set_header Host $host;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header REMOTE-HOST $remote_addr;
|
||
proxy_set_header Upgrade $http_upgrade;
|
||
proxy_set_header Connection $connection_upgrade;
|
||
proxy_http_version 1.1;
|
||
add_header X-Cache $upstream_cache_status;
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
#### 5. An error occurs when pulling an image `tls: failed to verify certificate: x509: certificate signed by unknown authority`
|
||
|
||
**Known Issue：** Certificate issue. Indicates that the certificate was issued by an unknown or untrusted certificate Authority (CA).
