Question

我已经在K8S集群中部署了微服务。以下是“舵图”详细信息-

CHART_NAME = eric-bss-sd-dxp-adaptation-staging，CHART_VERSION = 1.0.262，NAMESPACE = anindya-ns

现在我想编写一个Python脚本，它将获取此版本的图表（即1.0.262）

如果您以前曾就此要求进行过工作或提出了建议，请提供帮助

我可以给您一些步骤，可能会有所帮助。

创建服务/吊舱/部署...，如下所示

SQL> with
  2  -- sample data
  3  t1 (pid, name) as
  4    (select 123, 'xyz' from dual union all
  5     select 234, 'pqr' from dual
  6    ),
  7  t2 (id, name, start_date, end_date) as
  8    (select 1, 'xyz', date '2020-01-01', date '2020-07-20' from dual union all
  9     select 2, 'xyz', date '2020-02-01', date '2020-05-30' from dual union all
 10     select 3, 'xyz', date '2020-06-30', date '2020-07-30' from dual union all
 11     --
 12     select 1, 'pqr', date '2020-04-30', date '2020-09-30' from dual union all
 13     select 2, 'pqr', date '2020-05-30', date '2020-09-30' from dual union all
 14     select 3, 'pqr', date '2020-06-30', date '2020-07-01' from dual
 15    )
 16  select a.pid,
 17         x.name,
 18         max(x.start_date) start_date,
 19         max(x.end_date)   end_date
 20  from t1 a join
 21      (
 22        -- start_date: always for the lowest  T2.ID value row
 23        -- end_date  : always for the highest T2.ID value row
 24        select b.name,
 25               first_value(b.start_date) over (partition by b.name order by b.id     ) start_date,
 26               first_value(b.end_date)   over (partition by b.name order by b.id desc) end_date
 27        from t2 b
 28       ) x
 29       on a.name = x.name
 30  group by a.pid,
 31           x.name
 32  order by a.pid;

       PID NAME START_DATE END_DATE
---------- ---- ---------- ----------
       123 xyz  01/01/2020 07/30/2020
       234 pqr  04/30/2020 07/01/2020

您可以在任何名称，全名，标签...等地方使用.Chart.Version。

使用kubectl命令来获取yaml文件，例如：-https://github.com/kubernetes/kubernetes/issues/24873

然后编写您自己的python代码以读取它，获取聊天版本。
