我希望在容器之间有一个共享目录:ftp
和s3fs
。到目前为止,我已经在docker compose文件中创建了一个名为s3
的卷。
如果我停止s3fs
在s3fs
容器中运行,那么我可以在ftp
容器中创建文件,它们将显示在/home/files
下的s3fs
侧。
但是,当运行s3fs
时,目录/home/files
保持为空,而我在ftp
中创建文件。
这就是我的/proc/mounts文件的样子:
/dev/sda2 /home/files ext4 rw,relatime,data=ordered 0 0
s3fs /home/files fuse.s3fs rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other 0 0
我相信fuse可能会覆盖我的docker卷,以前有人遇到过这个问题吗?

您可以通过下一种方式在docker容器中装载s3
1.添加到Dockerfile
RUN apt-get install -y fuse s3fs
RUN mkdir /root/.aws
RUN touch /root/.aws/.passwd-s3fs && chmod 600 /root/.aws/.passwd-s3fs
COPY entrypoint.sh ./
RUN chmod 700 entrypoint.sh
ENTRYPOINT entrypoint.sh
2.使用下一个脚本创建entrypoint.sh
#!/bin/sh
echo "$AWS_CREDS" > /root/.aws/.passwd-s3fs
echo "$BUCKET_NAME /srv/files fuse.s3fs _netdev,allow_other,passwd_file=/root/.aws/.passwd-s3fs 0 0" > /etc/fstab
mount -a
<your old CMD or ENTRYPOINT>
3.在docker-compose.yml中添加下一个
<your-container-name>:
image: ...
build: ...
environment:
- AWS_ID="AKI..."
- AWS_KEY="omIE..."
- AWS_CREDS=AKI...:2uMZ...
- BUCKET_NAME=<YOUR backed name>
devices:
