在 apache karaf 启动时安装预编程功能

Question

我正在开发一个使用 apache karaf 的 opendaylight 项目。在程序开始时，我需要 karaf 安装一些功能。目前（并且可行）我手动将其输入到 shell 中并安装了功能：

$ bin/karaf
Apache Karaf starting up. Press Enter to open the shell now...
100% [========================================================================]
Karaf started in 9s. Bundle stats: 409 active, 410 total

    ________                       ________                .__  .__       .__     __
    \_____  \ ______   ____   ____ \______ \ _____  ___.__.|  | |__| ____ |  |___/  |_
     /   |   \\____ \_/ __ \ /    \ |    |  \\__  \<   |  ||  | |  |/ ___\|  |  \   __\
    /    |    \  |_> >  ___/|   |  \|    `   \/ __ \\___  ||  |_|  / /_/  >   Y  \  |
    \_______  /   __/ \___  >___|  /_______  (____  / ____||____/__\___  /|___|  /__|
            \/|__|        \/     \/        \/     \/\/            /_____/      \/


Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown OpenDaylight.

opendaylight-user@root>feature:install odl-restconf odl-mdsal-apidocs odl-openflowplugin-flow-services-rest odl-openflowplugin-app-table-miss-enforcer odl-openflowplugin-nxm-extensions odl-restconf-all odl-openflowplugin-flow-services
opendaylight-user@root>

所有这些都有效。但是，我需要的是在开始时自动安装此功能。我知道有一个shell.init.script 文件，我试图将此行添加到它的底部：

feature:install odl-restconf odl-mdsal-apidocs odl-openflowplugin-flow-services-rest odl-openflowplugin-app-table-miss-enforcer odl-openflowplugin-nxm-extensions odl-restconf-all odl-openflowplugin-flow-services

但是当我这样做时，我收到以下错误：

/opt/opendaylight-0.11.0/etc/shell.init.script: Command not found: feature:install

我也知道将 featuresBoot 元素添加到 org.apache.karaf.features.cfg

featuresBoot = odl-restconf（为了便于测试，我将其缩短为一个功能）

我得到这个错误：

org.apache.felix.resolver.reason.ReasonException: Unable to resolve root: missing requirement [root] osgi.identity; osgi.identity=odl-restconf; type=karaf.feature; version="[1.10.0,1.10.0]"; filter:="(&(osgi.identity=odl-restconf)(type=karaf.feature)(version>=1.10.0)(version<=1.10.0))" [caused by: Unable to resolve odl-restconf/1.10.0: missing requirement [odl-restconf/1.10.0] osgi.identity; osgi.identity=odl-restconf-nb-rfc8040; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-restconf-nb-rfc8040/1.10.0: missing requirement [odl-restconf-nb-rfc8040/1.10.0] osgi.identity; osgi.identity=odl-restconf-common; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-restconf-common/1.10.0: missing requirement [odl-restconf-common/1.10.0] osgi.identity; osgi.identity=odl-mdsal-broker; type=karaf.feature; version="[1.10.0,1.10.0]" [caused by: Unable to resolve odl-mdsal-broker/1.10.0: missing requirement [odl-mdsal-broker/1.10.0] osgi.identity; osgi.identity=org.opendaylight.controller.sal-binding-broker-impl; type=osgi.bundle; version="[1.10.0,1.10.0]"; resolution:=mandatory [caused by: Unable to resolve org.opendaylight.controller.sal-binding-broker-impl/1.10.0: missing requirement [org.opendaylight.controller.sal-binding-broker-impl/1.10.0] osgi.wiring.package; filter:="(&(osgi.wiring.package=org.osgi.service.blueprint)(version>=1.0.0)(!(version>=2.0.0)))"]]]]]

所以，我可以说 karaf 至少承认 shell.init.script 和 org.apache.karaf.features.cfg，但是我显然使用了错误的语法。我已经用尽了谷歌搜索来找到正确的语法或找到这方面的例子。事实上，当我为这个问题使用谷歌搜索时，我得到的建议是“使用 shell.init.script”文件，没有示例或文档链接来说明如何使用它。

例如，这里有一个类似的问题script to run commands at start of apache karaf，但答案确实不完整或不完整。我不知道在哪里放置建议的命令等。

无论如何，我希望这里有人可以告诉我在 shell.init.script 或 org.apache.karaf.features.cfg 中使用什么特定命令来实现这一目标。 （目标是等效的初始化命令来完成我可以手动成功完成的操作，如顶部所述）

更新： 我也试过这种类型的命令：

echo "feature:install odl-restconf odl-mdsal-apidocs odl-openflowplugin-flow-services-rest odl-openflowplugin-app-table-miss-enforcer odl-openflowplugin-nxm-extensions odl-restconf-all odl-openflowplugin-flow-services" | /opt/opendaylight-0.11.0/bin/karaf

这也不起作用。我没有收到任何错误消息，我只知道我的 restconf 不起作用。有趣的是，我确实看到所有功能都通过管道传输到 karaf shell 中，并且 shell 似乎确实冻结了（似乎它正在处理命令），但是在光标返回给我之后就不行了。

感谢@jamo，因为他的回答让我找到了答案。我只需要将它添加到 etc/org.apache.karaf.features.cfg：

featuresBoot = odl-restconf,odl-mdsal-apidocs,odl-openflowplugin-flow-services-rest,odl-openflowplugin-app-table-miss-enforcer,odl-openflowplugin-nxm-extensions,odl-restconf-all,odl-openflowplugin-flow-services, 25921329-8d07-420b-af13-94948bf1a78d

我相信诀窍在于拥有最终的 25921329-8d07-420b-af13-94948bf1a78d，这是默认 cfg 文件中的一些十六进制值，我确保它保留在那里。

我们只在上游 ODL 中使用 org.apache.karaf.features.cfg 文件 系统测试。你可以在this log 中看到它，但具体来说，这里是 它看起来像我们的 yangtools 工作之一：

您对 featuresBook 的问题有一个错字，但我猜那是 只是一个错字不是你的问题。很奇怪 feature:install 有效， 但不是 featuresBoot。
