我有一个可运行的私有 OpenStack 安装，并正在尝试使用 juju。如下所示：
dave@dave-D945GTP:~$ juju version
1.11.2-raring-amd64
dave@dave-D945GTP:~$ juju sync-tools
listing the source bucket
found 6 tools
found 6 recent tools (version 1.10.0)
listing target bucket
found 0 tools in target; 6 tools to be copied
copying tools/juju-1.10.0-precise-amd64.tgz, download 2205kB, uploading
copying tools/juju-1.10.0-precise-i386.tgz, download 2306kB, uploading

copying tools/juju-1.10.0-raring-i386.tgz, download 2312kB, uploading
copied 6 tools
到目前为止，一切似乎都很好。但是，它无法引导：
dave@dave-D945GTP:~$ juju -v bootstrap

成功创建了一个名为“juju-cece0b9817a68cba4780784bf0663e45”的 swift 容器，其中包含一个工具“目录”（包含通过 juju sync-tools 获得的六个文件）和一个 bootstrap-verify 文件。
我的 .juju/environments.yaml 如下：
default: openstack
environments:
## https://juju.ubuntu.com/get-started/openstack/
openstack:
type: openstack
# Specifies whether the use of a floating IP address is required to give the nodes
# a public IP address. Some installations assign public IP addresses by default without
# requiring a floating IP address.

# Globally unique swift bucket name
control-bucket: juju-cece0b9817a68cba4780784bf0663e45
# Usually set via the env variable OS_AUTH_URL, but can be specified here

读了一些资料后，我确定我显然需要上传“精确”图像并运行 juju image-metadata。我创建了元数据，如下所示...
dave@dave-D945GTP:~/.juju$ juju image-metadata -a amd64 -e http://10.103.8.1:5000/v2.0 -i d7e2ea12-cb50-4687-b5e1-d90f0656164a -n openstack -r RegionOne -s precise
...并将生成的文件移动到 juju-cece0b9817a68cba4780784bf0663e45 容器中的“streams/v1”。
juju bootstrap -v 产生了完全相同的结果。
根据我在（可能不相关的）错误报告中发现的一些内容，我还尝试将 openstack-index.json 和 openstack-imagemetadata.json 分别复制到 index.json 和 imagemetadata.json。
再次，juju bootstrap -v 产生了完全相同的结果。
有什么建议么？
答案1
您需要创建第二个存储桶，名为 juju-dist，用于上传图像数据文件。然后添加
public-bucket-url: <URL TO JUJU-DIST BUCKET>
到您的 environment.yaml 文件中。这应该可以解决“无法找到精确图像”错误。
