# Apache SkyWalking OAP Server Docker Files<imgsrc="http://skywalking.apache.org/assets/logo.svg"alt="Sky Walking logo"height="90px"align="right"/>**SkyWalking**: an APM(application performance monitor) system, especially designed for microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.# NoticeThis image can only connect to Elasticsearch **7** when setting `SW_STORAGE`=`elasticsearch`.# How to use this image## Start a `standlone` container with `H2` storage```$ docker run --name oap --restart always -d apache/skywalking-oap-server:8.0.0-es7```## Start a `standlone` container with `elasticsearch` storage whose address is `elasticsearch:9200````$ docker run --name oap --restart always -d -e SW_STORAGE=elasticsearch -e SW_STORAGE_ES_CLUSTER_NODES=elasticsearch:9200 apache/skywalking-oap-server:8.0.0-es7```# ConfigurationWe could set up environment variables to configure this image. They are defined in [backend-setup](https://github.com/apache/skywalking/blob/v8.0.0/docs/en/setup/backend/backend-setup.md). # Extend imageIf you intend to override or add config files in `/skywalking/config`, `/skywalking/ext-config` is the location for you to put extra files.The files with the same name will be overridden, otherwise, they will be added in `/skywalking/config`.If you want to add more libs/jars into the classpath of OAP, for example, new metrics for OAL. These jars can be mounted into `/skywalking/ext-libs`, then`entrypoint` bash will append them into the classpath. Notice, you can't override an existing jar in classpath.# License[Apache 2.0 License.](/LICENSE)
