BOSH CLI 预计会在路径中找到地图……但找到了 '[]interface {}'答案

【问题描述】：

与另一个问题非常相似，但略有不同。尝试了接受的答案，但仍然没有运气。

运行命令时出现此错误：

bosh -d prometheus deploy -n pfg-prometheus-boshrelease/manifests/prometheus.yml -o replace_vars.yml

预计会在路径“/instance_groups/name=prometheus2/jobs/name=prometheus2/properties/prometheus/scrape_configs/job_name=bosh/static_configs/targets？”找到地图？但找到'[]interface {}'

replace_vars.yml：

- type: replace
  path: /instance_groups/name=prometheus2/jobs/name=prometheus2/properties/prometheus/scrape_configs/job_name=bosh/static_configs/targets?/-
  value: 192.168.123.26:9190

清单部分：

- name: prometheus2
    properties:
      prometheus:
        rule_files:
        - ...
        scrape_configs:
        - file_sd_configs:
          - files:
            - /var/vcap/store/bosh_exporter/bosh_target_groups.json
          job_name: prometheus
          relabel_configs:
          - action: keep
            ...
          - regex: (.*)
            ...
        - job_name: bosh
          scrape_interval: 2m
          scrape_timeout: 1m
          static_configs:
          - targets:
            - localhost:9190

正确的路径是什么？

编辑：我查看了bosh cli ops files，但找不到像我这样的例子。

我也多次偶然发现这一点，但从未找到适用于该用例的解决方案。我通常做的一种解决方法是升级一步。以您为例：

/tmp/replace-vars.yml:

- type: replace
  path: /instance_groups/name=prometheus2/jobs/name=prometheus2/properties/prometheus/scrape_configs/job_name=bosh/static_configs/0
  value:
    targets:
    - 192.168.123.26:9190
    - localhost:9190

/tmp/test-manifest.yml:

instance_groups:
- name: prometheus2
  jobs:
    - name: prometheus2
      properties:
        prometheus:
          rule_files:
          - abc
          scrape_configs:
          - file_sd_configs:
          - files:
            - /var/vcap/store/bosh_exporter/bosh_target_groups.json
          job_name: prometheus
          relabel_configs:
          - action: keep
          - regex: (.*)
          - job_name: bosh
          scrape_interval: 2m
          scrape_timeout: 1m
          static_configs:
          - targets:
            - localhost:9190

由bosh int /tmp/test-manifest.yml -o /tmp/replace-vars.yml插值：

instance_groups:
- jobs:
  - name: prometheus2
      properties:
        prometheus:
          rule_files:
          - abc
          scrape_configs:
          - file_sd_configs:
          - files:
            - /var/vcap/store/bosh_exporter/bosh_target_groups.json
          job_name: prometheus
          relabel_configs:
          - action: keep
          - regex: (.*)
          - job_name: bosh
          scrape_interval: 2m
          scrape_timeout: 1m
          static_configs:
          - targets:
            - 192.168.123.26:9190
            - localhost:9190
  name: prometheus2
