可能已經發生一時間了，但是最近才注意到 XD。
|
||
|
||
在使用 `docker-compose down` 或是 `docker-compose up`，都會出現下面這個訊息：
|
||
|
||
```bash
|
||
/snap/docker/2746/lib/python3.6/site-packages/paramiko/transport.py:32: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6.
|
||
from cryptography.hazmat.backends import default_backend
|
||
```
|
||
|
||
雖然已經確定使用 Python 3.10，查看 docker-compose 版本也確實發現它還是使用 Python 3.6：
|
||
|
||
```bash
|
||
xxxx@xxxx:~/oooo/ooxx$ sudo docker-compose version
|
||
/snap/docker/2746/lib/python3.6/site-packages/paramiko/transport.py:32: CryptographyDeprecationWarning: Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography. The next release of cryptography (40.0) will be the last to support Python 3.6.
|
||
from cryptography.hazmat.backends import default_backend
|
||
docker-compose version 1.29.2, build unknown
|
||
docker-py version: 5.0.3
|
||
CPython version: 3.6.9
|
||
```
|
||
|
||
這是因為 `docker-compose` 這個命令已經過時了，請改用 `docker compose` 就可以了。<br>
|
||
要是習慣改不過來，不妨就加個alias吧：
|
||
|
||
```bash
|
||
alias docker-compose='docker compose'
|
||
```
