Helm CLI使用--set时对逗号错误拆分导致值被截断的问题求助

This is a super common gotcha with Helm's --set flag—Helm interprets commas as separators between multiple key-value pairs, so when you run:

helm install your-chart . --set connString=service_name:8080,password=xxxxx=,abortConnect=False

Helm actually splits this into three separate assignments:

• connString=service_name:8080
• password=xxxxx=
• abortConnect=False

That's exactly why only the first part ends up in your connString value. Here are three reliable ways to fix this:

1. Escape commas with backslashes #

Add a backslash before each comma in your value to tell Helm it's part of the string, not a separator:

helm install your-chart . --set connString=service_name:8080\,password=xxxxx=\,abortConnect=False

2. Wrap the value in single quotes (shell-friendly) #

Use single quotes around the entire value to prevent your shell from parsing the commas, and Helm will receive the full string as-is:

helm install your-chart . --set connString='service_name:8080,password=xxxxx=,abortConnect=False'

This works great in bash/zsh—single quotes preserve all characters inside them, including commas and equals signs.

3. Use --set-string for explicit string values #

If you want to ensure Helm treats the value as a string (and doesn't try to parse it as a boolean or number), combine quotes with --set-string:

helm install your-chart . --set-string connString='service_name:8080,password=xxxxx=,abortConnect=False'

After using any of these methods, your template's {{ .Values.connString }} will render the full connection string instead of just the first segment.
