所以我有以下Dockerfile:
FROM adoptopenjdk/openjdk13-openj9:alpine-jre
WORKDIR /opt/Lavalink
COPY Lavalink.jar Lavalink.jar
COPY application* ./
RUN if [[ -f "./application.local.yml" ]]; then mv "./application.local.yml" "./application.yml"; fi
EXPOSE 2333
CMD ["java", "-jar", "Lavalink.jar"]
然后由以下docker-compose.yml启动:version: '2.4'
services:
lavalink:
network_mode: host
container_name: lavalink
image: skyrabot/lavalink:main
restart: always
ports:
- '2333:2333'
但是,当我尝试连接到服务或检查docker ps
时,我看到没有端口发布。docker ps的输出:
> docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e35e7cdea0a4 skyrabot/lavalink:main "java -jar Lavalink.…" 7 minutes ago Up 7 minutes lavalink
对我在这里可能做错的事情有任何想法吗? 最佳答案
问题出在network_mode: host
行中。提供此选项时,Docker将使用主机网络而不是桥接它,并且它将完全忽略已配置的端口。您应该禁用/删除该行,或将其更改为network_mode: "bridge"
。有关更多信息,请参见https://docs.docker.com/compose/compose-file/compose-file-v2/#network_mode。
