A single quoted string in JSON array format

Reports a single quoted string in JSON array format.

JSON array form, must use double-quotes (") around words not single-quotes ('). Otherwise, Docker build will fail.

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Dockerfile


# all the commands below will fail RUN ['/bin/bash', '-c', 'echo hello'] ADD ['binaryA.jar', 'binary2.jar', 'destination/'] COPY ['binaryA.jar', 'binary2.jar', 'destination/']

After the quick-fix is applied:

RUN ["/bin/bash", "-c", "echo hello"] ADD ["binaryA.jar", "binary2.jar", "destination/"] COPY ["binaryA.jar", "binary2.jar", "destination/"]
