docker - 具有数据持久性的 Elasticsearch docker 镜像

Question

我的 Linux AWS EC2 计算机上的 Elasticsearch docker 镜像的数据持久性存在问题。

我像这样启动容器:

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 \
  -v $PWD/elasticsearch/data:/usr/share/elasticsearch/data \
  -e "discovery.type=single-node" \
  docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4

问题出在 -v $PWD/elasticsearch/data:/usr/share/elasticsearch/data 行。在 Mac 上，一切正常，我可以在关闭容器后保留我的数据，但在 Linux 计算机上，我在容器中的 /usr/share/elasticsearch/data 目录上遇到权限错误。

错误(第3行是关键部分):

我需要添加什么才能使其在 Linux 上运行？

Answer 1

这会起作用。

设置权限:

sudo mkdir -p $PWD/elasticsearch/data
sudo chmod 777 -R $PWD/elasticsearch/data

然后:

docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 \
  -v $PWD/elasticsearch/data:/usr/share/elasticsearch/data \
  -e "discovery.type=single-node" \
  --name elasticsearch \
  docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4
