我正在尝试使用Packer来构建我正在处理的webapp的docker镜像。每当我运行packer build时，当它到达运行runit食谱的步骤时，我会得到Build 'docker' errored: Error executing Chef: Non-zero exit status: 137
我查看了137，发现这是与kill -9通常相关的退出代码。在大多数情况下，这意味着系统的内存运行严重不足，系统正在尝试进行补偿。
我试图找到最小的再现，我想出了这个打包器配置：
{
"builders":[{
"type": "docker",
"pull": false,
"image": "silkstart/basic_server",
"export_path": "image.tar",
"run_command":[
"-d",
"-i",
"-t",
"--memory-reservation",
"1G",
"{{.Image}}",
"/bin/bash"
]
}],
"provisioners":[
{
"type": "chef-solo",
"cookbook_paths": ["cookbooks", "vendor/cookbooks"],
"data_bags_path": "data_bags",
"roles_path": "roles",
"environments_path": "environments",
"run_list": [
"recipe[runit]"
]
}
],
"post-processors": [
{
"type": "docker-import",
"repository": "silkstart/docker_test",
"tag": "0.1"
}
]
}
当我在此配置上运行packer build时，这是我的输出：
TMPDIR=/opt/shared packer build packer_files/docker_test.json
docker output will be in this color.

我不完全确定导致代码137的原因，任何帮助都会受到赞赏。

我包含了Chef的完整调试输出的要点。它更冗长，主要是因为它似乎是Ohai为获取信息所做的所有尝试。

此处没有任何引用似乎表明存在内存不足错误，至少在docker主机上是这样。

显然，作为设置过程的一部分，runit的一个后init脚本执行kill -s HUP 1。为什么我不完全确定，但正如他们在那里所指出的那样，在trap '' HUP和apt-get install runit之前做trap HUP之后就完全解决了我的问题。

检查主机上的OOM日志。您还可以使用execute_command配置值将日志级别转为调试。

这个答案似乎对我有用：a valid date format to work
我必须通过转到Docker选项卡＆gt;来增加分配给docker的内存资源。偏好＆gt;先进
