docker - 每个主机有多个vespa docker容器？

Question

PB:我试图在两个不同的主机上部署5个vespa容器，但是我没有成功建立我的vespa节点。

我在第一个主机上分别命名了3个容器vespa0，vespa1，vespa2和端口8080、8081和vespa4，分别具有端口8080、8081和8082

我这样启动vespa容器

sudo docker run --detach --net=host --name vespa0 --hostname admin_paul0 --privileged --volume $PWD/sample-apps:/vespa-sample-apps --publish 8080:8080 vespaengine/vespa

然后，通过以下方式部署应用程序:

sudo docker exec vespa0 bash -c '/opt/vespa/bin/vespa-deploy prepare /vespa-sample-apps/site_search_multi_node_on_multi_server/src/main/application && /opt/vespa/bin/vespa-deploy activate'

当我写命令时

sudo docker exec vespa0 bash -c '/opt/vespa/bin/vespa-get-cluster-state'

群集检测到两个主机上的节点，但只有一个处于运行状态。

Cluster site:
site/distributor/0: down
site/distributor/1: down
site/distributor/3: down
site/distributor/4: up
site/storage/0: down
site/storage/1: down
site/storage/3: down
site/storage/4: up

特此配置应用程序

您有什么技巧可以使它起作用吗？ :)

Answer 1

您必须隔离网络才能使此工作正常进行，因为Vespa会使用其他可能会冲突的其他端口范围(即--net = host)。在裸机主机上运行，​​您可以使用macvlan网络驱动程序为容器分配跨主机ip，否则您需要设置NPT或类似的东西。
