如何獲取 bash 中編寫的 ansible 模塊的參數？

Question

我寫了一個 ansible 模塊是 bash。它工作正常，但如果想將 arguments 傳遞給該模塊並在 bash 模塊中讀取它們，我該怎么做。請幫忙

- name: get top processes consuming high cpu
  gettopprocesses:
    numberofprocesses: 5

在庫中我有 bash 腳本 library/gettopprocesses.sh

#!/bin/bash
TPCPU=$(ps aux --sort -%cpu | head -${numberofprocesses}
echo "{\"changed\": false, "\msg\": {"$TPCPU"}}"
exit 0

我這樣寫你的 bask：你必須添加 source $1 來指定你有 args

#!/bin/bash
source $1
NUMBERPROC=$numberofprocesses
TPCPU=$(ps aux --sort -%cpu | head -${NUMBERPROC})

printf '{"changed": %s, "msg": "%s", "contents": %s}' "false" "$TPCPU" "contents"
exit 0

您可以添加一個測試來檢查是否給出了正確的 arg：

#!/bin/bash
source $1

if [ -z "$numberofprocesses" ]; then
    printf '{"failed": true, "msg": "missing required arguments: numberofprocesses"}'
    exit 1
fi

NUMBERPROC=$numberofprocesses
TPCPU=$(ps aux --sort -%cpu | head -${NUMBERPROC})

printf '{"changed": %s, "msg": "%s", "contents": %s}' "false" "$TPCPU" "contents"
exit 0
